Question

How do ya do this inverse thingy
-2+7c=40

Answer 1

c=6

Explanation:

-2+7c=40

so if your 2 is negative we want to make it equal 0 so add 2 and we have to do that on the other side of the =

We now have 7c=42

now we want the c to be alone so we do 42/7

our final answer is c=6

i hope that helps explain the process

Answer 2

c = 6

Explanation:

-2+7c = 40

=>add 2 to the both sides

7c = 42

=>divide both sides by 7

c = 6
