Answer:
D
Step-by-step explanation:
Given the 2 equations
2x + 3y = 11 → I(1)
y = x - 3 → (2)
Substitute y = x - 3 into (1)
2x + 3(x - 3) = 11 ← distribute parenthesis and simplify left side
2x + 3x - 9 = 11
5x - 9 = 11 ( add 9 to both sides )
5x = 20 ( divide both sides by 5 )
x = 4
Substitute x = 4 into (2) for corresponding value of y
y = 4 - 3 = 1
Solution is (4, 1 ) → D
