Question 643154
You can only simplify as they are not set equal to anything
...
4(x-3y) + 2(3x-7) + y
Distribute
4(x) - 4(3y) + 2(3x) + 2(-7) + y
4x - 12y + 6x - 17 +y
Combine like terms
{{{highlight_green(10x - 11y - 17)}}}
...
9(-3x + 5y - 7(x+6y))
Distribute inside the parentheses first
9(-3x + 5y - 7(x) - 7(6y))
9(-3x + 5y - 7x - 42y)
9(-10x - 37y)
9(-10x) - 9(37y)
{{{highlight_green(-90x - 333y)}}}
...
(3x+2y)-(2x-2y) + y
Distribute the negative
3x + 2y - 2x + 2y + y
Combine like terms
{{{highlight_green(x + 5y)}}}
