Answer:

-2

Step-by-step explanation:

<em>Since,</em>

<em>it given that</em>

<em>x = -3</em>

<em>y = 4</em>

<em>and the equation is:</em>

<em>2x + y = ?</em>

<em />

<em>Thus we can substitute:</em>

<em>2(-3) + 4 = ?</em>

<em>-6 + 4 = -2</em>

<em>Hence,</em>

<em>? = -2</em>

4x - 3y = -28<br>x + 5y = 39 cant seem to be able to figure the answer for this​
Rus_ich [418]

value of x = -1 and value of y=8

Step-by-step explanation:

We need to solve the system of equations:

4x - 3y = -28\,\,\,(1)\\x + 5y = 39\,\,\,(2)

Multiply eq(2) with 4 and subtract with eq(1)

4x-3y=-28\\4x+20y=156\\-\,\,\,-\,\,\,\,\,\,\,\,\,\,\,\,\,\,-\\--------\\-23y=-184\\y=\frac{-184}{-23}\\y=8

So, value of y=8

Now, finding value of x by putting value of y in equation 2

x+5y=39\\x+5(8)=39\\x+40=39\\x=39-40\\x=-1

So, value of x = -1

value of x = -1 and value of y=8

Which is a better buy?
pav-90 [236]

Answer: I would say to go with "2-cup carton of pineapple juice for $1.04"

Step-by-step explanation:

If you want more pineapple juice for a cheaper price go with 2-cup carton for $1.04 The reason I say this is because 2 quarts equal 8 cups, so if you multiply the 2 cups and price by 4 you get 8-cups= $4.16 which is cheaper.
