Question

The solution of the equation ax + b = 0 is ______.

विकल्प

• ` x = a/b`

• `x = -b`

• `x = (-b)/a`

• `x = b/a`

Answer 1

The solution of the equation ax + b = 0 is `underlinebb(x = (-b)/a)`.

Explanation:

Given equation is ax + b = 0

⇒ ax = – b   ...[Transposing b to RHS]

⇒ `(ax)/a = (-b)/a`  ...[Dividing both sides by a]

∴ `x = (-b)/a`

Hence, the solution of the equation ax + b = 0 is `x = (- b)/a`.
