Answer:

x = 2.25, y = 2.5

Step-by-step explanation:

-2x + 2y = -2 .............equ (1)

2x + 3y = 12 .............equ (2)

equ (1) + equ (2)

-2x + 2y = -2

+ 2x + 2y = 12

=> 0 + 4y = 10

=> 4y/4 = 10/4

=> y = 2½

Substitute for y in equ (2)

i. e, 2x + 3y = 12

=> 2x + 3(10/4) =12

=> 2x + 30/4 = 12

=> 2x = 12 - 30/4

=> 2x = (48 - 30)/4

=> 2x = 18/4

=> 8x = 18

=> x = 18/8

=> x = 2^2/8 or 2.25

x = 2.25, y = 2.5

The cost of 5 cans of dog food is $4.35.At the price,how much do 11 cans of dog foo cost.
IgorLugansk [536]
<h2>Greetings!</h2>

Answer:

11 cans cost $9.57

Step-by-step explanation:

There are two ways of doing this, one being the longer and the other being the shorter.

The shorter one is simply multiplying the number by the new number over 5:

4.35 * \frac{11}{5}

This works because this finds the amount the 5 has increased from 5 to 11 and muliplies the number by this.

4.35 * \frac{11}{5} = 9.57

So 11 cans cost $9.57
