Multiply the second equation by -2, then subtract it from the first equation. It should be
6x+5y=300
-6x-14y=-570
-9y=-270
y=30
Multiply the second equation by -2, then subtract it from the first equation. It should be
6x+5y=300
-6x-14y=-570
-9y=-270
y=30
Answer:
$30
Step-by-step explanation:
Solving the equation given simultaneously to get the x and y variable;
6x + 5y = 300... (1) × 1
3x + 7y = 285... (2) × 2
Using elimination method, we will multiply equation 1 by 1 and equation 2 by 2 as shown above to have;
6x + 5y = 300... 3
6x + 14y = 570... 4
Subtracting equation 3 from 4, we have;
5y-14y = 300-570
-9y = -270
y = 270/9
y = 30
Since y represent the cost for each chocolate gift basket, the cost of each chocolate gift basket will be $30
