7-(3x-1)=5x ....given
:
7-3x+1=5x.....distributed -1(3x-1) which equals -3x+1
:
8-3x=5x.....combined like terms on left
:
8x=8.....added 3x to both sides
:
highlight%28x=1%29divided both sides by 8 to isolate the variable x

7-3x%2B1=5x Distribute


7%2B1=5x%2B3x Add 3x to both sides.


8=8x Combine like terms.


8%2F8=x Divide both sides by 8 to isolate "x"


1=x Reduce
