To solve for

You can first divide both sides of the equation by 3, giving:

then add 3 to both sides:

3(x+1)=21

-3 -3

x+1=18

-1 -1

x=17?

The numbers are aligned kind of wrong, but you get the idea.

Is the answer right? - April 6th 2010, 07:47 PMxSquall

Thank you. On problems like:

6(3d+5) =75, do I take a similar approach? - April 7th 2010, 12:39 AMmathaddict
