Answer

x=5

Work Step by Step

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