Is (4,2) a solution of the system?

Answer:
B
Step-by-step explanation:
Plug x as 4 and y as 2.
2 = 4 - 2
2 = 2 True
2 = 3(4) + 4
2 = 12 + 4
2 = 16 False
Answer:
No.
Step-by-step explanation:
Substitute 4 (as x) and 2 (as y) into the 2 equations to see if they fit.
y = x - 2
2 = 4 - 2
2 = 2
The first equation is true for (4,2).
Now try the 2nd one.
y = 3x + 4
2 = 3(4) + 4
2 ≠ 16
So the 2nd equation is not true for (4,2).
Either one not true makes the solution incorrect.
