Answer:

Yes.

Step-by-step explanation:

We'll substitute in the values in both equations.

[tex]2x-3y=-5[/tex]        [tex]4x-4y=-4[/tex]

[tex]2(2)-3(3)=-5[/tex]   [tex]4(2)-4(3)=-4[/tex]

Distribute.

[tex]4-9=-5[/tex]             [tex]8-12=-4[/tex]

Simplify.

[tex]-5=-5[/tex]                [tex]-4=-4[/tex]

Yes, it is a solution. You can plug the equations into Desmos to check.
