Answer: x= [tex]-\frac{7}{2} = -3 \frac{1}{2} = -3.5[/tex]

Step-by-step explanation:

−(7−2x)+7=−7

To find the opposite of 7−2x, find the opposite of each term.

−7−(−2x)+7=−7

The opposite of −2x is 2x.

−7+2x+7=−7

Add −7 and 7 to get 0.

2x=−7

Divide both sides by 2.

[tex]x = \frac{-7}{2}[/tex]

Fraction  −7/2 can be rewritten as −2/7 by extracting the negative sign.

[tex]x = -\frac{7}{2}[/tex]
