3x-4=13
First you want all your x's on one side, and all your ordinary numbers on the other.
Add four to both sides to get rid of the "-4" part on the left.
Your new equation is 3x = 17
Divide each side by 3 to find X.
x= 17/3 or 5 2/3

Hello!

First, you'd want to add 4 to each side. For example, you'll want to add 4 to 4 and 13. After you've done that the equation should now look like this

3x=17

Next, you'll need to divide each side by 3, meaning you'll divide 17 and 3 by 3. Your equation will now look like...

x=5.6 repeating (5.66666...)

Your answer will be x=5.6

I ope this helps!
