x=3
Step-by-step explanation:
Simplifying
4 (4x + - 3) = 36
Reorder the terms:
4 (-3 + 4x) = 36
(-3 * 4 + 4x * 4) = 36
(-12 + 16x) = 36
Solving
-12 + 16x = 36
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '12' to each side of the equation.
-12 + 12 + 16x = 36 + 12
Combine like terms: - 12 + 12 = 0
0 + 16x = 36 + 12
16x = 36 + 12
Combine like terms: 36 + 12 = 48
16x = 48
Divide each side by '16'.
x = 3
Simplifying
x = 3

4 (-4x-3) = 36
We move all terms to the left:
4 (-4x-3) - (36) = 0
We multiply parentheses
-16x-12-36=0
We add all the numbers together, and all the variables
-16x-48=0
We move all terms containing x to the left, all other terms to the right
-16x=48
x=48/-16
x=-3
