Answer:
(7, 3 )
Step-by-step explanation:
Given the 2 equations
x = 4y - 5 → (1)
2x + 3y = 23 → (2)
Substitute x = 4y - 5 into (2)
2(4y - 5) + 3y = 23 , that is
8y - 10 + 3y = 23
11y - 10 = 23 ( add 10 to both sides )
11y = 33 ( divide both sides by 11 )
y = 3
Substitute y = 3 into (1) for corresponding value of x
x = 4(3) - 5 = 12 - 5 = 7
solution is (7, 3 )
