ANSWER
The solution is
x=-3,y=-2
EXPLANATION
First equation
3x – 3y = –3
Second Equation:
5x – y = –13
Multiply the second equation by 3 to get:
Third equation:
15x-3y=-39
Subtract the first equation from the third equation:


Divide both sides by 12,

Put x=-3 into the first equation:


Group like terms,



The solution is
x=-3,y=-2
Answer:
The inequality is 
Step-by-step explanation:
Given : Lionel plays trumpet for a minimum of 45 minutes on the days that he practices. If x is the number of days that Lionel practices and y is the total number of hours he spends practicing.
To find : Which inequality represents this situation?
Solution : He plays trumpet for a minimum of 45 minutes

If x is the number of days that Lionel practices then he practices for at least
hours
y is the total number of hours he spends practicing
So, the inequality form is:

i.e, 0.75x is greater than y.
