2x-4 divided by 7 = x-1 divided by 9
What does x eual
2x-4 divided by 7 = x-1 divided by 9
What does x eual
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.
