Question

If mFGK = 5w + 7 and mFGH = 114, find w

Answer 1

The answer is 21.4 because if you subtract 7 to 114 it gives you 107, once you’ve done that you divide 107 and 5. That should give you 21.4

Answer 2

21.4 = w

Explanation:

114 = 5w + 7

Subtract 7 from both sides:

114 - 7 = 5w + 7 - 7

Simplify:

107 = 5w

Divide 5 from both sides:

107 ÷ 5 = 5 ÷ 5w

Simplify:

21.4 = w
