Simplifying
37 + 8x = 4 (7 + - 1x)
37 + 8x = (7 * 4 + - 1x * 4)
37 + 8x = (28 + - 4x)
Solving
37 + 8x = 28 + - 4x
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '4x' to each side of the equation.
37 + 8x + 4x = 28 + - 4x + 4x
Combine like terms: 8x + 4x = 12x
37 + 12x = 28 + - 4x + 4x
Combine like terms: - 4x + 4x = 0
37 + 12x = 28 + 0
37 + 12x = 28
Add '-37' to each side of the equation.
37 + - 37 + 12x = 28 + - 37
Combine like terms: 37 + - 37 = 0
0 + 12x = 28 + - 37
12x = 28 + - 37
Combine like terms: 28 + - 37 = - 9
12x = - 9
Divide each side by '12'.
x = - 0.75
Simplifying
x = - 0.75
