Answer:
A. One solution
Step-by-step explanation:
We are given a system of equations and are asked to find whether it has a certain solution.
y = x + 4
2x + 2 = y
Since both equations end with y, we can substitute them from back to back.
x + 4 = 2x + 2
Subtract 2 from both sides :
x + 2 = 2x
Subtract x from both sides :
x = 2
Solve for y now that you have x by subtituting x with the value.
(2) + 4 = y
2(2) + 2 = y
6 = y
6 = y
Therefore this means that the system of equations is one solution because it intersects at one point (2, 6).
