Solve the system by substitution 3x+y=-16 and y=-x-4

x=-6

y=2

hope that helps

x = - 6

y = 2

Step-by-step explanation:

Equations

3x+y=-16

y=-x-4

Solution

Put y in the second equation into the first equation

3x - x - 4 = - 16

2x  - 4     = - 16

2x = - 16 + 4

2x = -12

2x/2 = -12/2

x = - 6

y = -x - 4

y = - -6 - 4

y = 6 - 4

y = 2

3x + y = - 16

3x + 2 = - 16

3x = -16 - 2

3x = - 18

3x/3 = -18/3

x = -6

this shows a reflection over the x-axis and is translated one unit down and 6 units to the right (x + 6, y - 1)

hope this !
