It should be plus 10 y at the 2nd lineNot minus 10 y at the 2nd line
Line 2: should be =10y (rightmost term)reason: negative times negative is positive
The answer is wrong
The second line, the "-10y" should be "+10y"
The first line should be +10 and not -10
Line 2 : -5 x -2y = 10yThe answer should not be negative.
2x(3x-y) - 5(3x-2y)= 6x^2 - 2xy - 15x + 10yThis should be the correct equation.
At the second line, it should be +10y and not -10y
2nd row: -10y should be +10y as - X - = +3rd row: x^2 and x is different4th row: 9x should be -9x and -2y-10y should be = -12y
NEGATIVE X NEGATIVEANS IS WRONG
The minus sign in (3x-2y) should switch to an addition sign in the second line.
The -10y from the second line should be positive
The line: 15x - 10y, should be 15x + 10y as negative 5 times negative 2y should be positive 10y.
Line 2: positive 10y
For the second line, instead of -10y it should be +10y as negative x negative = positive.
in the 3rd row, the -10y should be +10y
One of the Mathematical Symbols in the second line is wrong. The answer should be:2x(3x-y)-5(3x-2y)=6xx-2xy-15x+10y=6x-2y-15x+10y
The answer should be:At line 2: should be +10y not - 10yAt the end it should be +8y
