bring y to the other side on first equation so that you will have
x= y + 4 and substitute y + 4 for x in second equation
3(y+4) - 5 = 2 and solve
3y + 12 - 5 = 2
3y +7 = 2
3y= -5
y= -5/3
plug the answer for y into either equation and solve
Solve the following system using elimination. If a single solution exists, write the solution as an ordered pair. Your answer will be an ordered pair, no solution, or infinitely many solutions
x-y=4
3x-5=2
