Question

Please help I keep getting them wrong.

Answer 1

(2, 2)

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).
