Step-by-step explanation:
1)3/y=9
- when we shift y from one side to another side of equal to sign, multiplication changes to division and vice versa.
- so it will become 3=9y
- then we'll shift 9 down
- so it becomes 3/9=y
- hence reducing in lowest term we get
- 1/3=y
- this is your answer.
2)75-5y
in this you have to put the value of y and find the answer
3)when you shift from one side to another in equal to addition becomes subtraction and vice versa
