Answer:
x = -1 and y = 1
Step-by-step explanation:
5x + 2y = -3 . . . . . . . (i)
x + 5y = 4 . . . . . . . (ii)
- Finding x in terms of y from eq. (ii) :-
x + 5y = 4
x = 4 - 5y
- Placing this value of x in eq. (i) :-
5(4 - 5y) + 2y = -3
20 - 25y + 2y = -3
-23y = - 23
<u>y = 1</u>
- Placing the value of y in eq. (i)
5x + 2(1) = -3
5x + 2 = -3
5x = - 5
<u>x = -1</u>

We'd divide.
This is because:
Gallons are much more than cups. If we cant to convert cups to gallons, we divide to get a smaller unit.
Example: There are 32 cups on the table. How many gallons are there?
32/amount of cups per gallon
32/16 = 2
2 gallons,
The answer is C.30. Because you multiply 6*5 and you get 30.
