Answer: x = -1, y = 1 ---------- (-1, 1)
Given the following system of equation
y = 2x + 3 --------------- equation 1
x - y = -2 ------------------ equation 2
These equations can be solve simultaneously
put the value of y in equation 2
x - (2x + 3) = -2
x - 2x - 3 = -2
Collect the like terms
x - 2x = -2 + 3
-x = 1
Divide both sides by -1
x = -1
To find y, put the value of x in equation 1
y = 2(-1) + 3
y = -2 + 3
y = 1
Therefore, x = -1 and y = 1 (-1, 1)
x = -1, y = 1
