-7+3x+15=75-5\left(2x+3\right)
Use the distributive property to multiply 3 by x+5.
8+3x=75-5\left(2x+3\right)
Add -7 and 15 to get 8.
8+3x=75-10x-15
Use the distributive property to multiply -5 by 2x+3.
8+3x=60-10x
Subtract 15 from 75 to get 60.
8+3x+10x=60
Add 10x to both sides.
8+13x=60
Combine 3x and 10x to get 13x.
13x=60-8
Subtract 8 from both sides.
13x=52
Subtract 8 from 60 to get 52.
x=\frac{52}{13}
Divide both sides by 13.
x=4
Divide 52 by 13 to get 4.
