So you already know that x will make the left side equal to 3.

OpenStudy (anonymous):

But to solve this, we need to get the bottom part on the right to 5 yet still keep it in proportion. To do this, we multiply the top and bottom by the denominator on the left (5) What is your new equation?

OpenStudy (anonymous):

3x5=16x-1

OpenStudy (anonymous):

1(6x-1) i mean

OpenStudy (anonymous):

Yes, but you want to keep it as an improper fraction. So 3*5=15. Now you just put 1*5 under it as the denominator. So now you have (6x-1)/5=15/5

OpenStudy (anonymous):

Next, we can simplify by saying 6x-1=15. You know what to do now?

OpenStudy (anonymous):

divide each side by 15

OpenStudy (anonymous):

No.

OpenStudy (anonymous):

When you have an equation with a variable, you always want to isolate the variable.

OpenStudy (anonymous):

What should we do first to get x by itself?

OpenStudy (anonymous):

divide each side by 6 i mean sorry
