Question

y = x + 8
X + y = 2
solve system by substitution

Answer 1

Answer:

x=-3 y=-5

Step-by-step explanation:

y = x + 8

X + y = 2

First take the first equation and input it into the second equation.

X+ (x+8)= 2

Now simplify

X+x+8=2

2x+8=2

    -8=-8

2x= -6

÷2   ÷2

x= -3.

Now that you have the x value, input it into the first equation to find y.

y= (-3) +8

y= -5
