Answer:
D. (2,5)
Step-by-step explanation:
For X:
2+2(5)=12
2+10=12
For Y:
5=2+3
Answer:
D
Step-by-step explanation:
Given the 2 equations
x + 2y = 12 → (1)
y = x + 3 → (2)
Substitute y = x + 3 into (1)
x + 2(x + 3) = 12 ← distribute and simplify left side
x + 2x + 6 = 12
3x + 6 = 12 ( subtract 6 from both sides )
3x = 6 ( divide both sides by 3 )
x = 2
Substitute x = 2 into (2) for corresponding value of y
y = 2 + 3 = 5
Solution is (2, 5 ) → D
