The best method for solving this is to cross-multiply (which is the same as multiplying both sides by 63 and then dividing).

You will then have:

9(2x - 4) = 7(x - 1)

or 18x - 36 = 7x - 7

Now subtract 7x from both sides:

18x - 36 = 7x - 7

-7x -7x

--------------------------------------

11x - 36 = -7

Add 36 to both sides:

11x - 36 = -7

+ 36 +36

11x = 29

Now divide by 11:

11x/11 = 29/11

or **x = 29/11**

Hello Rebecca,

For this problem use the cross multiplication. Multiply (2x - 4) by 9 and (x - 1) by 7.

Next, use distributive property and get rid of brackets, you'll get 18x - 36 = 7x - 7

Now you need to isolate the variable x. For that subtract 7x from both sides of the equation. You'll get

11x - 36 = -7

Now, add 36 on both sides of the equation.

11x = 29

Divide both sides by 11

**x = 29/11 (answer)**

Hope this helps you.
