3x-2y=12 what is x

3x-2y=12

3x=2y+12        Move the y piece to the other side

x=2y/3+12/3    Divide by 3 to isolate x

x=2y/3+4         Simplify

We can't give a specific answer...for instance, if y = -6, x = 0. But if y = 0 , x =4.

All we can do is to specify x in terms of y.

Add 2y to the equation and then divide by 3

3x = 12 + 2y

x = (12 + 2y) / 3

And that's x in terms of y
