2x-\left(-20\right)=-2\left(-2\right)
Multiply 4 and -5 to get -20.
2x+20=-2\left(-2\right)
The opposite of -20 is 20.
2x+20=4
Multiply -2 and -2 to get 4.
2x=4-20
Subtract 20 from both sides.
2x=-16
Subtract 20 from 4 to get -16.
x=\frac{-16}{2}
Divide both sides by 2.
x=-8
Divide -16 by 2 to get -8.
