Question

3x/2 = 15?

Answer 1

Solve for x

Answer 2

i know that much i need to know how.

Answer 3

You have 3x/2 = 15, you cannot just pull x out so you need to "peel" off the other numbers to get it.

Answer 4

3x=30
x=10

Answer 5

The idea is to teach, not do the work.

Answer 6

i agree^

Answer 7

So what do i start off with?

Answer 8

If side A is being divided by 2, how could you get the 2 out of there?

Answer 9

multiply?

Answer 10

Correct, \[\frac{A}{2} \times \frac{2}{1} = A\] And whatever you do to one side of the equation, you MUST do to the other.

Answer 11

so it comes out to 6x=30?

Answer 12

and then divide by 6?

Answer 13

Almost, you have \[\frac{3x}{2} \times \frac{2}{1}\] so the 2s cancel out and leave you with 3x on the left.

Answer 14

ohhh. so divide 3 and 30?

Answer 15

You got it. :)
