Answer:

X = -7/2

Step-by-step explanation:

Answer:

x = -7/2

Step-by-step explanation:

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

          -7   -7

Start by subtracting -7 from both sides.

-(7-2x) = -14

Divide both sides by -1 to eliminate the negatives.

-(7-2x) = -14

---------     -------

-1               -1  

Simplify.

7-2x = 14

Subtract -7 from both sides.

-2x = -7

Divide both sides by -2

-2x = -7

-----    ----

-2        -2

x= -7/2

Check if -7/2 by plugging it back into the equation: (-7/2 = -3.5)

-(7-2(-3.5))+7 = -7
