Please help I keep getting them wrong.

Answer:
(2, 2)
Step-by-step explanation:
Since we know that y = x, we can substitute that into the first equation and solve for y.
-(y) + 3y = 4
2y = 4
y = 2
And once more, since we know that y = x, we now know that x is also 2.
Therefore, the solution is (2, 2).
