If 3x + 5y = 2 and 2x - 6y = 20 what is 5x - y

Hey!

We have:

... 3x + 5y = 2

... 2x - 6y = 20

In order to get 5x - y , we will need to add both the equations.

3x+5y=2

2x-6y=20

...5x - y = 22

Hence, the required answer is 22.

Hope it helps!

step-by-step explanation:

6 (donuts) divided by 3 is 2.

so 2/3 means 2 times 2, which is 4/6.

you get two and your friend gets four.

so, converting firstly the mixed fractions to improper fractions and then "adding".
