Asap plz me.doyley can't explain it correctly

As I get this a system equation. So to solve this you need to plug in y=-3x+5 into second given equation (5x-4y=3). This way you’ll solve for x. So: 5x-4(-3x+5)=-3. 5x+12x-20=-3. 17x=17. x=1. Now that we know x let’s plug it in into first equation by doing so we’ll solve for y. y=-3(1)+5. y=2. So, we know that x=1 and y=2.
