Answer:
d
Step-by-step explanation:
Given the 2 equations
2x - y = 11 → (1)
3x - 2y = 6 → (2)
Multiply (1) by - 2 and adding will eliminate y
- 4x + 2y = - 22 → (3)
Add (2) and (3) term by term
(3x - 4x) + (- 2y + 2y) = (6 - 22)
- x = - 16 ( multiply both sides by - 1 )
x = 16
Substitute x = 16 into (1) or (2) for corresponding value of y
(1) : 32 - y = 11 ( subtract 32 from both sides )
- y = - 21 ( multiply both sides by - 1 )
y = 21
Solution is (16, 21 ) → d
Answer:
It's d. (16,21).
Step-by-step explanation:
2x - y = 11 .............(1)
3x – 2y = 6...........(2)
Multiply the first equation by -2:
-4x + 2y = -22.......(3)
Adding (2) + (3):
-x = -16
x = 16.
Substitute for x in equation (1):
2(16) - y = 11
-y = 11-32 = -21
y = 21.
