2. The solution of the equation ax + b = 0 is
a
(a) x =
(b) x = - b
b
-b
b
(c) x-
(d) x =
a
a​

Answer 1

$\underline{\orange{\bf Given :-}}$

$\implies$ax + b = 0

$\underline{\orange{\bf To \: Find :-}}$

$\implies$Value of x

$\underline{\orange{\bf Solution :-}}$

$\implies$ax + b = 0

$\implies$ax = - b

$\implies$x = (- b)/a

$\underline{\orange{\bf Verification :-}}$

We have,

$\implies$ax + b = 0

Substituting the value of x,

$\implies$a{(- b)/a} + b = 0

$\implies$(- ba)/a + b = 0

$\implies$- b = - b
