okay so first step is you set them equal to each other to find x!!

so 4x + 13 = 6x + 19

then solve; so subtract 4 from both side and get 13 = 2x + 19

then subtract 19 from both sides and get -6 = 2x

then divide 2 by both side and get x = -3

then you have to plug x = -3 back in to find y, it doesn’t matter which equation!!

so you do y = 4(-3) + 13 and solve that and you get y = 1

you’ll get the same answer if you do it for the other equation. HOPE THIS HELPS!!
