2x+5-4x=-20
Subtract 4x from both sides.
-2x+5=-20
Combine 2x and -4x to get -2x.
-2x=-20-5
Subtract 5 from both sides.
-2x=-25
Subtract 5 from -20 to get -25.
x=\frac{-25}{-2}
Divide both sides by -2.
x=\frac{25}{2}
Fraction \frac{-25}{-2} can be simplified to \frac{25}{2} by removing the negative sign from both the numerator and the denominator.
