Question

3x-7y=2 solve for x. Can you show how you do it?

Answer 1

1)  3x-7y=2
2)  If you're solving for x, you want to isolate it, so move the -7y to the right:
          3x = 7y + 2
3)  Now, to get x by itself, you divide both sides by 3
          3x/3 = (7y + 2)/3
4)  You get:
           x = 7/3y + 2/3 

Answer 2

So, 3 * 4 = 12 , 7 * 1.5 = 10. 12-10 = 2 so x= 4<span /><span />
