Can someone check this? QRST is a parallelogram. Find x and y. I got : y-4x=9 y=4x+9 -x+4=y -x+4=4x+9 -5=5x x=1 & y=3

Nope. Since 9=y-4x and y=-x+4, then 9=-x+4-4x which leads to 9=-5x+4 Solve it and x=-1 Now going back to 9=y-4x plug x=-1 in 9=y+4 solve for y and its y=5

or with the other equation with x=-1 which is y=-x+4 y=1+4 y=5
