Question

-(7-2x) + 7 = -7

What is X?

Answer 1

Answer: x=
`-(7)/(2) = -3 (1)/(2) = -3.5`

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.

`x = (-7)/(2)`

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

`x = -(7)/(2)`
