# How do you solve the equation: 45 = 7x - 4?

Jul 2, 2015

Get $x$ on the left side, and the numerical values on the right side, then solve for $x$.

#### Explanation:

$45 = 7 x - 4$

Subtract $7 x$ from both sides.

$- 7 x + 45 = - 4$

Subtract $45$ from both sides.

$- 7 x = - 49$

Multiply both sides times $- 1$

$7 x = 49$

Divide both sides times $7$.

$x = 7$
