$x = 13$ $x = 13$

First subtract 20 from both sides:

$20 (- 20) + 25 x = (- 20)$ $20 (-20) + 25x = (-20)$
$25 x = 325$ $25x = 325$

This gets x as the only term on the left hand side.
Divide both sides by the co-effcient of x (25), so that you find the answer for 1 x.

$\frac{25 x}{25} = \frac{325}{25}$ $(25x)/25 = 325 / 25$
$x = 13$ $x = 13$
