x/5-g=a solve for x

OpenStudy (anonymous):

bring the g and 5 to the left side, we have to isolate x by itself.

OpenStudy (anonymous):

I'm confused.

OpenStudy (anonymous):

\[\frac{ x }{ 5 } - g = a\] Now add g to both sides: \[\frac{ x }{ 5 } = a + g\] Then multiply both sides by 5: \[5 \times \frac{ x }{ 5 } = 5 \times (a + g)\] x = 5(a+g)

OpenStudy (anonymous):

exactly like that, but I wanted you to try for yourself.

@tyram203 So, if you are confused, let's walk through the steps...

OpenStudy (anonymous):

I think I understand that type of problem now but its others that I don't get.

"Solving for" just means undoing all the "stuff" around the variable you need to solve for. First subtract or add to move extra stuff to the other side, then multiply or divide to "strip off" the coefficient from the variable if necessary.
