A + b = 90
a = 2b - 15
2b - 15 + b = 90
3b - 15 = 90
3b = 90 + 15
3b = 105
b = 105/3
b = 35 <== second angle
a = 2b - 15
a = 2(35) - 15
a = 70 - 15
a = 55 <== first angle
J+K+B+L=1000
K=2J
B=3J
L=100
1000-100=900
J+(2J)+(3J)=900
6J=900 Divide both sides by J.
J=150
Jim gets $150
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
