Answer:
$2000
Step-by-step explanation:
Answer:
4x +3y = 7; 1 ≤ x ≤ 9; 1 ≤ y ≤ 9
(x, y) = (1, 1)
Step-by-step explanation:
If you simply add the numbers, you have ...
(x+y) +(3x+2y) +8 +9 = 24
This simplifies to ...
4x +3y = 7
Perhaps the other "equations" in the "system of equations" are the constraint inequalities ...
The smallest possible value of both x and y is 1, which would satisfy this equation:
4·1 + 3·1 = 7
Using the expression (x+y) +(3x+2y) +8 +9 = 24, suitable values for x and y are 1 and 1.
_____
We have written one equation, which in this context only has one solution for the two variables. It seems likely that we need to know more about the game card in order to write a system of equations.
