-2y-(-8y-2) = -2y + 8y + 2 = 6y + 2

2(3x + 16) - 7x = 6x + 32 - 7x = -1x + 32 = 32 - x

-x + 6 + (-3) + x + (-4) = -x + 6 - 3 + x - 4 = 3 - 4 = -1

ways

Step-by-step explanation:

Given that a shelf contains n separate compartments. There are r indistinguishable marbles

The marbles are identical so they can be placed in any order.

Let us consider the places available for placing these r marbles

No of compartments available =n

Marbles to be placed = r

Since marbles are identical and order does not matter

number of ways the r marbles can be placed in the n compartments

= nCr

=\frac{n!}{r!(n-r)!}
