Answer 2

Answer: a = -9

❍ Solution :-

$\sf →15a + 24 = 12a - 3$

➸ Bringing R.H.S. to L.H.S. ,

$\sf →15a - 12a + 24 + 3 = 0$

$\sf →3a + 27 = 0$

➸ Finding the value of a,

$\sf →3a = - 27$

$\sf →a = \dfrac{ - \cancel{27}}{\cancel{3}}$

$\sf →\fbox{a = - 9}$

Hence, the value of a is equal to -9.
