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)
