Question
The solution of the equation ax + b = 0 is ______.
Options
` x = a/b`
`x = -b`
`x = (-b)/a`
`x = b/a`
Solution
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`.
