QUESTION 9 Solve for R: R - 2 = W

Answer 1

Explanation:

R-2=W

R-2(+2)=W+2

R=W+2

Key concept:

x+(−x)=0

If we have a+x=b, adding the opposite of a to both side we have:

a+x+(−a)=b+(−a)⟺x=b−a

Answer 2

The formula is:

R = W + 2

Work/explanation:

Rearrange the formula for R.

All we should do is add 2 to each side :

R - 2 = W

R = W + 2

Hence, this is the right answer.
