Answer:
you could use 3,5,1 as your answer, but I have a feeling you are expected to answer x = 15 / (1 - 2y) It depends on what you have been told.
Step-by-step explanation:
Take out x as a common factor.
I suspect there are many possible answers -- well more than 1 unique answer.
x (1 - 2y) = 15 Divide by 1 - 2y
x = 15 / (1 - 2y)
1 - 2y = 3
-2y = 2
y = -1
What does that give you?
1 - 2(-1) = 3
x = 15/3
x = 5
1- 2y = 5
- 2y = 4
y = -2
x = 15 / 5
x = 3
1 - 2y = 15
-2y = 15 - 1
-2y = 15
y = - 7
x = 15 / 15 = 1
