- I. 6x + y = 25 II. 2x + 3y = 27
Question 1:
I. 6x + y = 25II. 2x + 3y = 27
A. if x > y
B. if x ≤ y
C. if x ≥ y
D. if x < y
Feedback Correct Option: D
According to the given equations:
I. 6x + y = 25
y = 25 – 6x
II. 2x + 3y = 27
2x + 3(25 – 6x) = 27
2x + 75 – 18x = 27
75 – 27 = 18x – 2x
48 = 16x
x = 3
y = 25 – 6x
y = 25 – 18 = 7
After comparison of both equations, the conclusion is x < y
According to the given equations:
I. 6x + y = 25
y = 25 – 6x
II. 2x + 3y = 27
2x + 3(25 – 6x) = 27
2x + 75 – 18x = 27
75 – 27 = 18x – 2x
48 = 16x
x = 3
y = 25 – 6x
y = 25 – 18 = 7
After comparison of both equations, the conclusion is x < y
