Question

URGENT!!! Find the value of 5w-2 given that −7w-7=7 . Simplify your answer as much as possible.

Answer 1

-12

Explanation:

-7w - 7 = 7 Add 7 to both sides

-7w = 14 Divide both sides by -7

w = -2 Plug -2 in for w in the first equation given

5w - 2

5(-2) - 2

-10 - 2

-12

Answer 2

-12

Explanation:

Find the value of 5w-2

We are given

−7w-7=7

Divide by 7

−7w-7=7

-w -1 = 1

Add 1 to each side

-w = 1+1

-w = 2

Multiply by -1

w = -2

Now we can find the value of

5w-2

5(-2) -2

-10 -2

-12
