Solving
40 + x = -10 + 3x
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-3x' to each side of the equation.
40 + x + -3x = -10 + 3x + -3x
Combine like terms: x + -3x = -2x
40 + -2x = -10 + 3x + -3x
Combine like terms: 3x + -3x = 0
40 + -2x = -10 + 0
40 + -2x = -10
Add '-40' to each side of the equation.
40 + -40 + -2x = -10 + -40
Combine like terms: 40 + -40 = 0
0 + -2x = -10 + -40
-2x = -10 + -40
Combine like terms: -10 + -40 = -50
-2x = -50
Divide each side by '-2'.
x = 25
Simplifying
x = 25
