#### 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
