Answer:
x= -1.2
Explanation:
Simplifying
-7 + 12 + -2x = 23 + 13x
Combine like terms: -7 + 12 = 5
5 + -2x = 23 + 13x
Solving
5 + -2x = 23 + 13x
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-13x' to each side of the equation.
5 + -2x + -13x = 23 + 13x + -13x
Combine like terms: -2x + -13x = -15x
5 + -15x = 23 + 13x + -13x
Combine like terms: 13x + -13x = 0
5 + -15x = 23 + 0
5 + -15x = 23
Add '-5' to each side of the equation.
5 + -5 + -15x = 23 + -5
Combine like terms: 5 + -5 = 0
0 + -15x = 23 + -5
-15x = 23 + -5
Combine like terms: 23 + -5 = 18
-15x = 18
Divide each side by '-15'.
x = -1.2
