Whats the answer for this

$51

Step-by-step explanation:

Let:

P= buckets of popcorn

S= soft drinks

First equation:

3p+7s=$52.50

Second Equation:

4p+1s=$20

Next:

multiply the first equation by 4 and the second by -3

First equation:

12p+28s=210

Second Equation:

-12p-3s=-60

Then:

25s=150

Then:

Divide each side by 25

S= $6 per soft drinks

Then:

4p+1(6)=20

Next:

subtract 6 from 6 and then subtract 6 from 20

Then:

4p=14

Then:

divide 4 from both sides

P= $3.50 per bucket of popcorn

Then:

6(3.50)+5(6)=$51

where is the rest of the

step-by-step explanation:

fa tha first one you gonna add y to both sides

it look like this

x-y+y=6+y

x=y+6

therefore your answer is

x =y+6

fa tha second one

you gonna flip tha equation

it gonna look like x-4y=y

then add 4 to both sides

it gonna look like tha

x-4 +4 =y +4

so therefore tha answer is x=y+4
