8x-7.2\times 1.5=7x-7\left(1+0.5\right)x+700
Add 1 and 0.5 to get 1.5.
8x-10.8=7x-7\left(1+0.5\right)x+700
Multiply 7.2 and 1.5 to get 10.8.
8x-10.8=7x-7\times 1.5x+700
Add 1 and 0.5 to get 1.5.
8x-10.8=7x-10.5x+700
Multiply 7 and 1.5 to get 10.5.
8x-10.8=-3.5x+700
Combine 7x and -10.5x to get -3.5x.
8x-10.8+3.5x=700
Add 3.5x to both sides.
11.5x-10.8=700
Combine 8x and 3.5x to get 11.5x.
11.5x=700+10.8
Add 10.8 to both sides.
11.5x=710.8
Add 700 and 10.8 to get 710.8.
x=\frac{710.8}{11.5}
Divide both sides by 11.5.
x=\frac{7108}{115}
Expand \frac{710.8}{11.5} by multiplying both numerator and the denominator by 10.
