x+10\left(2x+5\right)=8
Multiply both sides of the equation by 2.
x+20x+50=8
Use the distributive property to multiply 10 by 2x+5.
21x+50=8
Combine x and 20x to get 21x.
21x=8-50
Subtract 50 from both sides.
21x=-42
Subtract 50 from 8 to get -42.
x=\frac{-42}{21}
Divide both sides by 21.
x=-2
Divide -42 by 21 to get -2.
