What does x equal if 3x 7 equals 5x 13?

Answer 1

First keep in mind that you're always trying to isolate your variable, in this case 'x'

3x - 7 = 5x - 13

+13 +13

---------------------------- Start by adding 13 to both sides.

3x + 6 = 5x

-3x -3x

------------------- The subtract 3x from both sides.

6 = 2x

-- --

2 2

---------------------- Divide each side by two

x = 3

3 * (3) - 7 = 5 * (3) - 13 Check your solution

9-7 = 15 - 13

2=2

Thus x=3
