Solve each system by substitution show your work step by step
y=-8
y=-2x-12

Given: (1) y = -8
           (2) y = -2x - 12

Using substitution method, we will solve this by following these steps.

Step 1: Substitute (1) to (2)
       (1) y = -8
       (2) y = -2x - 12
           -8 = -2x - 12
Step 2: Add 12 to both sides of the equation
         -8 + 12 = -2x - 12 + 12
                  4 = -2x
Ste 3: Divide both sides with -2
               4 / 2 = -2x / -2
                    2 = x
                     x = 2

Therefore, the solution of the system is x = 2 and y = -8

I’m vary good with science if you need with that

Using the rise/run rule. you would get 2/6.simp. 1/3
