Answer:
The equations that are equal to 15-8y=-11 are...
- Number 1
- Number 4
the initial statement is:

and then:

So the second statement is false because f should be multiply by e, not by d so is option C)
X>Y
X=7Y
3X=7+4Y
X=?
Y=?
----------------------------
3*7=7+4Y
21Y=7+4Y
21Y-4Y=7
17Y=7
Y=7/17
----------------------
X=7*7/17
X=49/17
