Answer:
(2, 3 )
Explanation:
4x - y = 5 → (1)
x + y = 5 ( subtract y from both sides )
x = 5 - y → (2)
substitute x = 5 - y into (1)
4(5 - y) - y = 5
20 - 4y - y = 5
20 - 5y = 5 ( subtract 20 from both sides )
- 5y = - 15 ( divide both sides by - 5 )
y = 3
substitute y = 3 into (2)
x = 5 - y = 5 - 3 = 2
solution is (2, 3 )
