ANSWER: (3,4)
Explanation: multiply both sides of the equation by -1
Sum the equations vertically to eliminate at least one variable so you should be left with 6x=18
Then divide by 6 on both sides
Substitute the value of x
Solve the equation
So you should have 4x3-5y=-8
Y=4
Then plug in the values you got, (3,4) into the original systems to see if what the values you got makes the statement true
