X=4
Y=1
You already have the equation done from that equation you cross out the -5x and 5x then add 13+4 it gives you 17 the add -7+34 it gives you 17 that’s when you get x. Now ones you have x plug in the 1 into any equation I prefer the ones that don’t have negative numbers, ok so the plug in 1 into the Y and then it would be 5x+4(1)=24, so you know 4(1) is 4 so then subtract 24-4 which gives you 20 and then bring down 5x and then divide 24/5 and then you get what X is and it is 5.
