Answer:
(2, 3 )
Explanation:
Given the 2 equations
4x + y = 11 → (1)
y = 3x - 3 → (2)
Substitute y = 3x - 3 into (1)
4x + 3x - 3 = 11, that is
7x - 3 = 11 ( add 3 to both sides )
7x = 14 ( divide both sides by 7 )
x = 2
Substitute x = 2 into (2) for corresponding value of y
y = (3 × 2) - 3 = 6 - 3 = 3
Solution is (2, 3 )
