what is G-8= 25 ? I told my teacher that g=17 but he said no because 17-8=9 not 25 so in my class we are using inverse so can I please get help?

Hi Eileen,

To solve the equation G - 8 = 25, you need to find the number that you would "start with" and subtract 8 that would give you a solution of 25.

In math terms, using inverses will help you identify this number. The inverse of subtraction is addition, so we can add 8 to both sides of the equation to determine G:

G - 8 = 25

G - 8 + 8 = 25+ 8

G = 33

To check: 33 - 8 = 25
