Solve the linear equation by using substitution x-y=-4 3x-y=-10

(-3, 1)

Step-by-step explanation:

x-y=-4

3x-y=-10

y=x-(-4)=x+4

3x-(x+4)=-10

3x-x-4=-10

2x-4=-10

2x=-10+4

2x=-6

x=-6/2

x=-3

-3-y=-4

y=-3-(-4)=-3+4=1

x=-3, y=1. (-3, 1).

i would go with the first one

step-by-step explanation:

hope this

the first one, all those points on the line just make a strait line.
