The solution to the equation 3 and 4 by elimination is x = -2 and y = -2
<h3>Simultaneous equation</h3>
2x = 3y + 2. (1)
3x = 5y + 4. (2)
2x - 3y = 2. (3)
3x - 5y = 4 (4)
- Multiply (3) by 3 and (4) by 2
6x - 9y = 6. (5)
6x - 10y = 8. (6)
- subtract (5) from (6) to eliminate x
-10y - (-9y) = 8 - 6
-10y + 9y = 2
-y = 2
y = -2
- substitute y = -2 into (3)
2x - 3y = 2. (3)
2x - 3(-2) = 2
2x + 6 = 2
2x = 2 - 6
2x = - 4
x = -4/2
x = -2

12 x 4.89 = 50.68
17 x 4.72 = 80.24
15 x 5.09 = 76.35
50.68 + 80.24 + 76.35 = $207.27

Answer:
The rate at which how many tokens a person loses per minute.
Step-by-step explanation:
If we move around the terms in the equation to fit standard form, it will be easier to determine the slope.
y = 50 - 2x
y = -2x + 50
We know that the slope is the coefficient of the x variable, so m = -2 or .
Since the slope is negative, we know that the line will go down as x increases. Since the slope is multiplied by the number of minutes x, we know that the slope represents the typical rate at which a guest spends tokens per minute. In simpler words, how many tokens a person loses every minute.
