Simplifying 3x + 2(4 + 6x) = 113 3x + (4 * 2 + 6x * 2) = 113 3x + (8 + 12x) = 113 Reorder the terms: 8 + 3x + 12x = 113 Combine like terms: 3x + 12x = 15x 8 + 15x = 113 Solving 8 + 15x = 113 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-8' to each side of the equation. 8 + -8 + 15x = 113 + -8 Combine like terms: 8 + -8 = 0 0 + 15x = 113 + -8 15x = 113 + -8 Combine like terms: 113 + -8 = 105 15x = 105 Divide each side by '15'. x = 7 Simplifying x = 7

Answer:

x=7

Step-by-step explanation:

To solve this the first thing we do is to use the distributive property: 3x+12x+8=113. Next, we combine the like terms: 3x+12x+8=113 then we simplify 15x+8=113. Then we subtract 8 from both sides of the equation: 15x=105. Then we divide by 15 to get the answer: 15x/15=105/15 which would give us: x=7.
