Answer:
Simplifying
50 + 15x = 100 + 20x
Solving
50 + 15x = 100 + 20x
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-20x' to each side of the equation.
50 + 15x + -20x = 100 + 20x + -20x
Combine like terms: 15x + -20x = -5x
50 + -5x = 100 + 20x + -20x
Combine like terms: 20x + -20x = 0
50 + -5x = 100 + 0
50 + -5x = 100
Add '-50' to each side of the equation.
50 + -50 + -5x = 100 + -50
Combine like terms: 50 + -50 = 0
0 + -5x = 100 + -50
-5x = 100 + -50
Combine like terms: 100 + -50 = 50
-5x = 50
Divide each side by '-5'.
x = -10
Simplifying
x = -10
