Answer

x = 1.5

Work Step by Step

Simplifying 2x + 4 = 7 Reorder the terms: 4 + 2x = 7 Solving 4 + 2x = 7 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-4' to each side of the equation. 4 + -4 + 2x = 7 + -4 Combine like terms: 4 + -4 = 0 0 + 2x = 7 + -4 2x = 7 + -4 Combine like terms: 7 + -4 = 3 2x = 3 Divide each side by '2'. x = 1.5 Simplifying x = 1.5
