Answer:
(1, 3 )
Step-by-step explanation:
Given the 2 equations
2x + y = 5 → (1)
- x + y = 2 → (2)
Rearrange (1) expressing y in terms of x by subtracting 2x fro both sides
y = 5 - 2x → (3)
Substitute y = 5 - 2x into (2)
- x + 5 - 2x = 2
- 3x + 5 = 2 ( subtract 5 from both sides )
- 3x = - 3 ( divide both sides by - 3 )
x = 1
Substitute x = 1 into (3) for corresponding value of y
y = 5 - 2(1) = 5 - 2 = 3
solution is (1, 3 )
