solve the following pair of simultaneous equations.
2x3y=13
3x+y=3

By elimination:
2x3y=13 ...(1)
3x+y=3 ...(2)
Multiply (2) by 3 and add to (1)
2x3y=13 ...(1)
9x+3y=9 ...(3)
Add(1) and (3)
11x = 22 ...(4)
Solve (4) to get
x=11
Substitute x=11 in (1) to solve for y. 
x=2, Substitute x=2 in (1) or (2). 2 is easier.

Thank you Jen.
yes, x=2.
