Answer:
x= -10
Simplifying
(4x + 20) = (x + -10)
Reorder the terms:
(20 + 4x) = (x + -10)
Remove parenthesis around (20 + 4x)
20 + 4x = (x + -10)
Reorder the terms:
20 + 4x = (-10 + x)
Remove parenthesis around (-10 + x)
20 + 4x = -10 + x
Solving
20 + 4x = -10 + x
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-1x' to each side of the equation.
20 + 4x + -1x = -10 + x + -1x
Combine like terms: 4x + -1x = 3x
20 + 3x = -10 + x + -1x
Combine like terms: x + -1x = 0
20 + 3x = -10 + 0
20 + 3x = -10
Add '-20' to each side of the equation.
20 + -20 + 3x = -10 + -20
Combine like terms: 20 + -20 = 0
0 + 3x = -10 + -20
3x = -10 + -20
Combine like terms: -10 + -20 = -30
3x = -30
Divide each side by '3'.
x = -10
Simplifying
x = -10
