For which equation is g = 0 not the solution?

Shalnov [3]

Answer:

3g = 30

Step-by-step explanation:

Well, lets check each one to see if any leaves g = 0

12g = 0 (Given)

÷12 ÷12 (Get "g" on its own)

g = 0 (0 ÷ 12 = 0)

We know it is not this one since g = 0

3g = 30 (Given)

÷3 ÷3 (Get "g" on its own)

g = 10 (30 ÷ 3 = 10)

This is our answer since g = 10 in this equation, and not g = 0 we know that this is our equation.

Just in case, I will do the other options just not as in-depth!

g + 8 = 8

-8 -8

g = 0

9g = 0

÷9 ÷9

g = 0

Hope this Helps! :)
