8 3/10 y−(3 5/11 −2 3/4 y)

Its an algebra question

Step-by-step explanation:

Distribute the negative sign. This basically changes the signs inside the parenthesis.

Combine like terms. I'll group them so that you can easily see them.

They're like terms because they have the same variable raised to the same power.

To add mixed numbers, add the whole numbers and then the fractions.

To be able to obtain the same denominator, multiply the first fraction by 4 and the second by 10.

When you have the same denominator, add numerators.

Simplify.

42/2=21

40/2=20

Because the fraction part is greater than 1, we must convert it to a mixed number. You can do this by dividing.

21/20=1

20

------

1

The one next to the equal sign is the whole number, the one in the remainder part is the numerator and 20 the denominator.

Rewrite this and add the whole number with 10.
