Let x represent the cost of corn dogs. Let y represent the cost of pretzels.
2x+3y=13
5x+6y=28
Multiply the first equation by two so that we can eliminate y.
Subtract:
4x+6y=26
5x+6y=28
-x=-2
x=2
4(2)+6y=26
8+6y=26
6y=18
y=3
3 x 2 = 6
6+2=8
Therefore, 2 pretzels and a corn dog would cost $8.
Answer:
y = -6
Step-by-step explanation:
y is multiplied by 3 and 20 is added to the sum. We undo these operations in reverse order.
First we subtract 20 from both sides of the equation:
3y = -18
Then we divide both sides of the equation by 3 to undo the multiplication.
y = -18/3 = -6
The solution is y = -6.
