That's "15 choose 5"

$\displaystyle{15 \choose 5} = \dfrac{15! }{5! 10!} = \dfrac{15 \cdot 14 \cdot 13 \cdot 12 \cdot 11}{5 \cdot 4 \cdot 3 \cdot 2 \cdot 1} = (15/(5(3))(14/2)(13)(12/4)(11)\\\\= 7(13)(3)(11)=231(13)=3003$

What does x and y equal if 3x-2 equal x-y equals 4

Alex17521 [72]

<em><u>Solution:</u></em>

Given that,

3x-2 equal x-y equals 4

Which means,

3x - 2 = x - y = 4

Therefore,

x - y = 4

Also,

3x - 2 = 4

Simplify above expression

3x - 2 = 4

3x = 4 + 2

3x = 6

Divide both sides by 3

x = 2

Substitute x = 2 in x - y = 4

2 - y = 4

y = 2 - 4

y = -2

Thus x is 2 and y is -2
