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

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

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.
