Do you have any clue where to start?

I changed it to slope intercept but the y intercept came out to 4 over 3?

shane_b · Answer

I would simply use substitution to solve this:

Looking at the first equation:
y-2x=-1

Which can be easily rearranged in terms of y:
y=2x-1

Plug this equation into the second original equation to get:
x + 3(2x-1) = 4 

Solving for x you will get 1.  Now just plug that into one of the original equations and solve for y:
y − 2(1) = −1
y = 1.
