16+8x+5=5\left(3+x\right)
Use the distributive property to multiply 8 by 2+x.
21+8x=5\left(3+x\right)
Add 16 and 5 to get 21.
21+8x=15+5x
Use the distributive property to multiply 5 by 3+x.
21+8x-5x=15
Subtract 5x from both sides.
21+3x=15
Combine 8x and -5x to get 3x.
3x=15-21
Subtract 21 from both sides.
3x=-6
Subtract 21 from 15 to get -6.
x=\frac{-6}{3}
Divide both sides by 3.
x=-2
Divide -6 by 3 to get -2.
