3[x2 + 4] = 15
Reorder the terms:
3[4 + x2] = 15
[4 * 3 + x2 * 3] = 15
[12 + 3x2] = 15
Solving
12 + 3x2 = 15
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 + 3x2 = 15 + -12
Combine like terms: 12 + -12 = 0
0 + 3x2 = 15 + -12
3x2 = 15 + -12
Combine like terms: 15 + -12 = 3
3x2 = 3
Divide each side by '3'.
x2 = 1
Simplifying
x2 = 1
Take the square root of each side:
x = {-1, 1}
