Answer: x = 1 and y = 5

We already know that x=y-4 so place the value of, "x" in the first equation, -10x+3y=5. So solve the steps like this:

-10(y-4) + 3y = 5

-10y + 40 + 3y = 5

-7y= 5-40

-7y= -35

y= -35/-7

y= 5

Now place the value of y in the first equation.

-10x + 3(5) = 5

-10x + 15 = 5

-10x= 5-15

x= -10/-10

x= 1

So x is 1 and y is 5

Brainliest pls if i am correct!

Ari stocks shelves at a grocery store.He puts 35 cans of juice in each display case.The case has 4 shelves with an equal number
ICE Princess25 [194]

Answer:

There are 8 cans on each of the equal shelves

Step-by-step explanation:

Total number of cans put in display = 35

Shelves with equal no of cans =  4 Shelves

And one shelf displays only 3 cans

Therefore, 4 shelves with equal no of cans + 1 shelf with 3 cans = 35 cans

Let us assume equal no. of cans be x

We get, 4x + 3 = 35

             4x = 35 - 3

             4x = 32

              x  = 32 ÷ 4

              x = 8

<u><em>Thus, 4 shelves with equal no of cans contains 8 cans each.</em></u>
