Step-by-step explanation:
there are 13 heart card in a deck of 52 cards
Answer:
(-4, -8)
Step-by-step explanation:
Note that x in terms of y is x = 2y + 12. Substitute 2y + 12 for x in the second equation:
5(2y + 12) + 3y = -44
or
10y + 60 + 3y = -44
Then 13y= -104, and y = -8
From the first equation we find x = 2(-8) + 12, or x = -16 + 12, or x = -4
Then the solution is (-4, -8)
