Answer
x =-1.333333333
Work Step by Step
Simplifying
16 = -3(x + -4)
Reorder the terms:
16 = -3(-4 + x)
16 = (-4 * -3 + x * -3)
16 = (12 + -3x)
Solving
16 = 12 + -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.
16 + 3x = 12 + -3x + 3x
Combine like terms: -3x + 3x = 0
16 + 3x = 12 + 0
16 + 3x = 12
Add '-16' to each side of the equation.
16 + -16 + 3x = 12 + -16
Combine like terms: 16 + -16 = 0
0 + 3x = 12 + -16
3x = 12 + -16
Combine like terms: 12 + -16 = -4
3x = -4
Divide each side by '3'.
x = -1.333333333
Simplifying
x = -1.333333333
