Answer:
(x, y) = (-1, 1)
Step-by-step explanation:
y = 2x + 3
x - y = -2 since y is equal to 2x + 3 we replace the y in the second equation with 2x + 3
x - (2x + 3) = -2 add like terms
-x - 3 = -2 add 3 to both sides
-x = 1 and x = -1
to calculate value of y we replace x with -1
y = 2x + 3
y = 2 (-1) + 3 and y = 1
