Answer:

x = -1

y = -3

Step-by-step explanation:

We can substitute the 2nd equation into the y of the first equation.

4x + 1 = x-2

Subtract x from both sides.

3x + 1 = -2

Subtract 1 from both sides.

3x = -3

x = -1

substitute this x value into the first equation

y = x - 2

y = -1 - 2 = -3
