\[x-4y=5\]

\[x=3y-2\]
OpenStudy (kamibug):
Substitute the value of x into the first equation. 3y - 2 - 4y = 5 y = -7 Now that you know the value of y, substitute it into the second equation to solve for x. :)
OpenStudy (anonymous):
how did you substitute?
OpenStudy (kamibug):
Well the second equation tells us the x is equal to 3y-2 so you just take 3y-2 and put in the place of x in the first equation. :) Get it?
