Question

Solve the following equation by using the substitution method. Write your answer as an order pair. Y + 3x = -1 2y -5x = 31

Answer 1

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?

Answer 2

Thanks So Much :)

Answer 3

as
y=31-3x
then
-12(31-3x)-5x=31
-372+36x-5x=31
31x=372+31
x=13
and y=-8

(13,-8)

Answer 4

Thanks =)

Answer 5

My tested result is (-3,8) for the ordered pair

Answer 6

Try testing (13,-8) in (y + 3x = -1)
