it is xd
i don't think you guys understand the question i asked
x=y+3 so u plug it in the other one 4(y+3)+y=2 4y+12=2 4y=-10 y=-10/4 y=-5/2
u have these 2 equations-\[4x+y=2 \]\[x-y=3\] add them together\[4x+y+x-y=2+3\]\[5x=5\]\[\frac{ 5x }{5 }=\frac{ 5 }{ 5 }\]\[x=1\]now we have x=1 put this value of x in any of the original equations to get y like i choose to put it in the second equation so\[x-y=3\]\[1-y=3\]\[y=-2\]
