5x-10+2\left(x+4\right)=-16
Use the distributive property to multiply 5 by x-2.
5x-10+2x+8=-16
Use the distributive property to multiply 2 by x+4.
7x-10+8=-16
Combine 5x and 2x to get 7x.
7x-2=-16
Add -10 and 8 to get -2.
7x=-16+2
Add 2 to both sides.
7x=-14
Add -16 and 2 to get -14.
x=\frac{-14}{7}
Divide both sides by 7.
x=-2
Divide -14 by 7 to get -2.
