Make the second problem and multiply everything by -1
5x+6y=50 -1(-x+6y=26) X-6y=-26 Eliminate the y and combine evrything 6x=24 Divide 6 both sides X=4 Then substitute the x -(4)+6y=50 -4+6y=50 Add 4 both sides 6y=54 Divide 6 and y=9 x=4
Multiply one of the equations by -1 5x+6y=50 -1(-x+6y=26) =x-6y=-26 Cancel out the 6y's add the rest 6x=24 X=4 Substitute x back into the original -(4)+6y=26 -4+6y=26 6y=30 Y=5 Get the point (4,5)
