40x+15=9\left(4x+2\right)
Use the distributive property to multiply 5 by 8x+3.
40x+15=36x+18
Use the distributive property to multiply 9 by 4x+2.
40x+15-36x=18
Subtract 36x from both sides.
4x+15=18
Combine 40x and -36x to get 4x.
4x=18-15
Subtract 15 from both sides.
4x=3
Subtract 15 from 18 to get 3.
x=\frac{3}{4}
Divide both sides by 4.
