how to solve questions without using models and replacing the models with algebra to make both sides equal when solving linear equations how to solve linear equations of with an unknown value.

look out for operators and remember to use logic. remember THE ORDER OF OPERATIONS and the laws. eg. THE COMMUTATIVE LAW OF MULTIPLICATION OF EXPENSIVE IMPORTED BONGANANIAN TILES

The key learning things are 1) we should take note on the terms in the equation 2) we should find out what is the variable 3)Expand the terms in the bracket

1: To write the unknown variable on the left 2: solve all using BODMAS on both sides before transferring 3: Transfer all the unknown on the left and all the numbers on the right

1. Finding unknown variable through the numbers given 2.Using distributive law when removing brackets 3. balancing the equation by adding or subtracting the numbers when required to move the number to other side

Have at least 1 variable in every line. Align the equal sign in every line Look out for special product rules Make sure the equations on both sides of the equal sign are equal at all times.

Key Learning Points 1. Linear Equations is using Algebra to substitute an unknown variable. 2. The unknown variable can either be a fraction or a whole number. 3. Linear Equations can be used to solve word problems (An alternative to Models) and real-world problems (An example is finding the cost of a shirt after discount).

ReplyDeleteto make both sides equal when solving linear equations

ReplyDeleteThe key learning things are

ReplyDelete1) we should take note on the terms in the equation

2) we should find out what is the variable

3)Expand the terms in the bracket

Balancing,lhs=rhs,constants!!!!!!!!!

ReplyDelete1. Make the two variables compatible

ReplyDelete2. Convert + to -

3. Organise the equation

All variables should be on the left-hand side and we are to use different operations to keep the equations balanced.

ReplyDelete1: To write the unknown variable on the left

ReplyDelete2: solve all using BODMAS on both sides before transferring

3: Transfer all the unknown on the left and all the numbers on the right

Key points:

ReplyDelete• Choosing the correct operations suited to keep equations balanced

• Expanding correctly

• Writing in equations. E.g. 2x = 2+2

x = 2

1. Finding unknown variable through the numbers given

ReplyDelete2.Using distributive law when removing brackets

3. balancing the equation by adding or subtracting the numbers when required to move the number to other side

Have at least 1 variable in every line.

ReplyDeleteAlign the equal sign in every line

Look out for special product rules

Make sure the equations on both sides of the equal sign are equal at all times.

LHS = RHS

Delete1. balancing

ReplyDelete2. taking notes of the terms

3.expanding everything

LHS= RHS

ReplyDeleteExpand both brackets

- Both sides of the equation must be equal.

ReplyDelete- When one side of the equation is affected, both sides are.

We should balance both terms, and each line should consist of the variable.

ReplyDelete1) no models allowed

ReplyDelete2) expansion

3) units

Linear equation is like finding an unknown term in an equation

ReplyDeleteUsing known terms to find the unknown

Balancing is used

1. Expand all the terms in the brackets

ReplyDelete2. Make both sides equal

3. No models

For question c, must put in decimal. But for question b, can put fraction or decimal.

ReplyDeleteIf shifting, minus need to become plus.

Key Learning Points

ReplyDelete1. Linear Equations is using Algebra to substitute an unknown variable.

2. The unknown variable can either be a fraction or a whole number.

3. Linear Equations can be used to solve word problems (An alternative to Models) and real-world problems (An example is finding the cost of a shirt after discount).
