x = 12
Step-by-step explanation:
Simplifying
6x + - 2 (-3x + - 5) = 154
Reorder the terms:
6x + - 2 (-5 + - 3x) = 154
6x + (-5 * - 2 + - 3x * - 2) = 154
6x + (10 + 6x) = 154
Reorder the terms:
10 + 6x + 6x = 154
Combine like terms: 6x + 6x = 12x
10 + 12x = 154
Solving
10 + 12x = 154
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-10' to each side of the equation.
10 + - 10 + 12x = 154 + - 10
Combine like terms: 10 + - 10 = 0
0 + 12x = 154 + - 10
12x = 154 + - 10
Combine like terms: 154 + - 10 = 144
12x = 144
Divide each side by '12'.
x = 12
Simplifying
x = 12
