Your Question:
2x+y=12
x-y=3
----------------------------------------------------------------------------
solve for x:
x-y=3 becomes x=y+3
----------------------------------------------------------------------------
substitute for x:
2(y+3)+y=12
----------------------------------------------------------------------------
Solve:
2y+6+y=12
3y+6=12
3y=6
y=2
----------------------------------------------------------------------------
substitute for y:
x-(2)=3
x=5
----------------------------------------------------------------------------
x=5 y=2 (5,2)<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<< Your answer!
----------------------------------------------------------------------------
Good luck with your homework!
