Answer :
a. 2x + 3 = 9 ( x = 3 )
=> Put x = 3 in the equation, we get
=> 2(3) + 3 = 9
=> 6 + 3 = 9
=> 9 = 9
L.H.S = R.H.S
Therefore x = 3 is the solution of the given equation.

c. 4x - 7 = 3x + 8 ( x = 15 )
Put x = 15 in the equation.
4(15) - 7 = 3(15) + 8
60 - 7 = 45 + 8
53 = 53
L.H.S = R.H.S
Therefore x = 15 is the solution of the given equation.
d. 2( x + 10 ) = 3( x - 2 ) ( x = 5 )
Put x = 5 in the equation, we get
2( 5 + 10 ) = 3( 5 - 2 )
2 × 15 = 3 × 3
30 is not equals to 9
L.H.S is not equals to R.H.S
Therefore x = 5 is not a solution of the given equation.

Hope it would help you
