How do I solve an equation like this, one with a negative in front of parentheses?
azamat

The factor outside the parentheses is -1. Distribute using that factor.

2 - (4 - <em>x</em>) = 7<em>x</em> - 5<em>x</em>

<em />

-1 * 4 = -4 and -1 * -<em>x</em> = <em>x</em>

<em />

2 - 4 + <em>x</em> = 7<em>x</em> - 5<em>x</em>

Simplify.

-2 + <em>x</em> = 2<em>x</em>

<em>x</em> = 2<em>x</em> + 2

-<em>x</em> = 2

<em>x</em> = -2

<h3>Answer:</h3>

<em>x</em> = -2
