Solve the following equation by using the substitution method. Write your answer as an order pair. Y + 3x = -1 2y -5x = 31
Multiply (y + 3x = -1) by 2. Then subtract the result from (2y - 5x = 31). This will eliminate y and enable you to find the value of x. Can you try this?
as y=31-3x then -12(31-3x)-5x=31 -372+36x-5x=31 31x=372+31 x=13 and y=-8 (13,-8)
My tested result is (-3,8) for the ordered pair
Try testing (13,-8) in (y + 3x = -1)
