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 - x) = 7x - 5x

-1 * 4 = -4 and -1 * -x = x

2 - 4 + x = 7x - 5x

Simplify.

-2 + x = 2x

x = 2x + 2

-x = 2

x = -2

<h3>Answer:</h3>

x = -2

Answer:

DE = 7.07 RS = 11.04 not congruent

Step-by-step explanation:

Formula:

$d=\sqrt{(x2-x1)^2 + (y2-y1)^2}$

D (5,0) E (0,-5)

$d=\sqrt{(0-5)^2 + ( -5 - 0)^2}$

$d=\sqrt{(-5)^2 + (-5)^2}$

$d=\sqrt{25+25}$

$d=\sqrt{50}$

d= 7.07

R (-5,-5) S (6,-6)

$d=\sqrt{(6-(-5))^2 + (-6 - (-5))^2 }$

$d=\sqrt{11^2 + (-1)^2}$

$d=\sqrt{121 + 1}$

$d=\sqrt{122}$

d= 11.04
