Question

2x+y=-2 5x+3y=-8 system of equations using substitution

Answer 1

Answer:

Step-by-step explanation:

Tripple 2x+y=-2

6x + 3y = - 6 And 5x + 3y = -8

Subtract the second equation from the first to get

X = -14

Now that we have x, we need to determine y.

(2 x -14) + y = -2

-28 + y = -2

Hence, -28 + 2 = - 26

Now thats the difference, but because we are adding y to -28 to get -2, y has to be positive

Hence, y must be 26

X= -14, Y= 26
