$\binom{3x - 1}{3}$
-
$\binom{2x + 5}{4}$
=
$\binom{5}{2}$


​

Answer 1

hi friend, I got the answer

Answer:

{3} {3x-1} - {4}{2x+5}={5}{2}

9x-3-8x-20=10

1x-23=10

x=10+23=33

x=33

verify

{3}{3*33-1}-{4}{2*33+5}

{3]{99-1}-{4}{66+5}

{3}{98]-{4}{71}

294-284=10

hence, the answer is right

hope it helps you
