I have no idea how to do this...

1. Is (2,3) as solution of the system

3x +4y = 18

2x - y =1?

you just plug in 2 and 3..

3(2)+4(3)=18

6+12=18

18=18

so yes, (2,3) is the solution for the first problem.

2x-y=1

again, plug in 2 and 3..

2(2)-1=1

4-1=1

3=1

so no, it's not the solution for the problem

hope I helped!
