Basically, you have to multiply to the other side.
1) you would multiply -x with 7 (will become -7x)
2)multiple -x with -2x (will become +2x power of 2)
3)multiple +5 with 7 (will become +35)
4)multiple +5 with -2x (will become +10x)
the whole equation would turn into (-7x+2x {power of 2}+35+10x. the combine like terms
