Are you asked to use a specific method?

godlovesme · Answer

x+3y= -1 
can u solve for x @love12609784

anonymous · Answer

no it doesnt ask me to use a specific method..

mathstudent55 · Answer

Then this is what I would do.
1) divide the second equation by 2
2) subtract the new second eq from the original first eq

mathstudent55 · Answer

The x's will cancel and you can solve for y.
Then plug in y into one of the original equations to find x.

mathstudent55 · Answer

Of course, you can also follow @Godlovesme 's suggestion above and solve the first equation for x, and use substitution.
