Answer:
(2, 5 )
Explanation:
given the system of equations
y = x + 3 → (1)
- 2x + y = 1 → (2)
substitute y = x + 3 into (2)
- 2x + x + 3 = 1 ( simplify left side )
- x + 3 = 1 ( subtract 3 from both sides )
- x = - 2 ( multiply both sides by - 1 )
x = 2
substitute x = 2 into (1) and solve for y
y = 2 + 3 = 5
solution is (2, 5 )
