Answer:
x = 4
Step-by-step explanation:
The steps we need to take:
1. Simplify left side.
2. Separate the variable and its coefficient from constants
3. Divide both sides by the coefficient to find "x
1) Simplify left side.
5(3x - 4) + 12 = 52
15x - 20 + 12 = 52
15x - 8 = 52
2) Separate the variable and its coefficient from constants by adding 8 to both sides.
15x - 8 + 8 = 52 + 8
15x = 60
3) Divide both sides by the coefficient to find x. (the coefficient is the number that comes before the variable)
15x / 15 = 60 / 15
x = 4
