How do i solve this problem? 9-x/5=3

9- x/5 = 3

Simplify both sides

9- x/5 = 3

9+ -1/5 x = 3

-1/5 x +9 = 3

Subtract 9 from both sides

-1/5 x +9-9 = 3-9

-1/5 x = -6

Multiply both sides by 5/(-1)

(5/-1 )*(-1/5 x )= (5/-1 ) * (-6)

x = 30

I hope that's help and if you have question please just let me know !

ANSWER

a) Use the homogeneous property of the binomial expansion to find the missing exponent

b) Use the binomial theorem to find the coefficient

EXPLANATION

The given binomial expansion is:

When we compare this to

We have

Therefore the of each term in the expansion must be 12.

Since the coefficient of x and y are unity, we use the formula

to find the coefficient.

Where n=12 and r=5(the exponent of the y-term).

Therefore the coefficient is

When we simplify further we get:
