Use substitution to solve the system of
equations.
y+1= -2x
4y + 8x = -4

x=2 and y=−18

Step-by-step explanation:

Solve x=2 for x:

x=2

Step: Substitute 2 for x in y=−18:

y=−18

y=−18

X=2 and Y =-18

2 and 1.

step-by-step explanation:

plug in each answer. 0 doesn't work, 1 does. so does 2. 4 doesn't:

0 = 1 is not true.

2 = 2 is true.

4 = 4 is true.

8 = 16 is not true.

hope this !
