Using substitution, determine the solution to the system of equations. Include a photo of your work
kiruha [24]

Answer:

I can't submit a photo but here:

x = 4, y = 16

(4,16)

You can choose whichever format

Step-by-step explanation:

We have x given to us already. Since we know the value of x, we can input the value into the other equation to solve for y

Solve:

Substitute 4 for x:

  • y = 2x + 8
  • y = 2(4) + 8
  • y = 8 + 8
  • y = 16

Our solution is x = 4 and y = 16, or (4,16)
