Answer: (-6,-5)
Step-by-step explanation:
2x - 2y = -2 ............ equation 1
3x - y = -13 ................ equation 2
solving by substitution method
from equation 2 , make y the subject of the formula, we have
y = 3x + 13 .............. equation 3
substitute equation 3 into equation 1 , we have
2x - 2 (3x + 13 ) = -2
2x - 6x - 26 = -2
-4x - 26 = -2
-4x = -2 +26
-4x = 24
x = 24/-4
x = -6
substitute x = -6 into equation 3 to get the value of y , we have
y = 3(-6) + 13
y = -18 +13
y = -5

I don't know if this is right or not but at least I attempted to help out.
And I'm very sorry if this answer is wrong.
45.9 L
Sweet bought enough bottles of sports drink to fill a big cooler for the skateboard team.
It took 25.5 bottles to fill the cooler and each bottle contained 1.8 liters.
Hence, the amount of water that the cooler will hold is equal to the total amount of water in 25.5 bottles.
Amount of water in 1 bottle=1.8 liters.
Amount of water in 25.5 bottle=25.5×1.8
=45.9 liters.
