5x+10-3\left(x+4\right)=0
Use the distributive property to multiply 5 by x+2.
5x+10-3x-12=0
Use the distributive property to multiply -3 by x+4.
2x+10-12=0
Combine 5x and -3x to get 2x.
2x-2=0
Subtract 12 from 10 to get -2.
2x=2
Add 2 to both sides. Anything plus zero gives itself.
x=\frac{2}{2}
Divide both sides by 2.
x=1
Divide 2 by 2 to get 1.
