Question

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

Answer 1

Answer: The answer to the equation 5w-2 is -12, since w is -2

Explanation:

We are given this equation:

−7w-7=7

==> −7w-7=7 ( add 7 to both sides)

==> -7w = 14 ( divide both sides by -7)

==> w = -2

Now that we know the value for w, we can solve the former equation;

==> 5w-2

=> 5(-2) -2 (distributive property)

=> -10 -2

=> -12

The answer to the equation 5w-2 is -12, since w is -2

Hope this helped! Have a good day ;)

Answer 2

Answer: The value of 5w - 2 is -12

Explanation:

First, solve for w in the equation of -7w-7=7

Add 7 to both sides to isolate -7w

You then get: -7w=14

Divide both sides by -7 to isolate w

You then get: w=-2

Then substitute -2 for w into the equation 5w-2

You then get: 5(-2)-2

Simplify and you get the final answer of -10-2=-12
