2X - 3Y = 6, Y - 6 = 14; find X and Y (don't know how)

Re: HELPPP PLEASE!!!
In the second equation, solve for Y. Now that you know the value of Y, replace Y in the firat equation with that value of Y. Then solve for X in the first equation. If you need more help, show us the steps you have taken so far so that we can determine where you are stuck.

If you can't tell that Y = 20, then you need CLASSROOM help.Jessicamaria said:I need serious help with this problem:

Re: HELPPP PLEASE!!!
what you need to do is solve for y. in this case, y equals 20. then, you plug y back in the first equation and then solve for x. it should look something like this:
Y-6=14
Y=20
Substitute into 2X-3Y=6:
2X-3(20)=6
2X-60=6
2X=66
x=33
X=33
Y=20
If you need to check this, just plug these 2 answers back into one of the original equations. you should come up with a true statement (ex.: 14=14)
Hope this helps!
