Answer:
➡Simplifying
(3x + 20) = x
(20 + 3x) = x
➡Remove parenthesis around (20 + 3x)
20 + 3x = x
➡Solving
20 + 3x = 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 + 3x + -1x = x + -1x
➡Combine like terms: 3x + -1x = 2x
20 + 2x = x + -1x
➡Combine like terms: x + -1x = 0
20 + 2x = 0
➡Add '-20' to each side of the equation.
20 + -20 + 2x = 0 + -20
➡Combine like terms: 20 + -20 = 0
0 + 2x = 0 + -20
2x = 0 + -20
➡Combine like terms: 0 + -20 = -20
2x = -20
➡Divide each side by '2'.
x = -10
▶therefore x = -10..
thank you
