If 3/x= 6, then x-1=

I tried to solve for x and got 2, but 3/2 does not equal 6??

Multiply by x.

3 = 6x

3/6 = 1/2 = x

Proof: 3/(1/2) = 3 * 2 = 6

Also if there is another problem similar to this one. Where the x is the denominator. Would you always move it to the other side?
Answered by Ms. Sue
You need to multiply both sides by the denominator.
