Solution

The correct option is A $\frac{b - a}{k - m}$
Given equation is: $k x + a = m x + b$
$\Rightarrow$ $k x - m x = b - a$
[mx is transposed as –mx, a is transposed as –a]
$\Rightarrow$ $x (k - m) = b - a$
$\Rightarrow x = \frac{b - a}{k - m}$

Find the value of x in kx+a=mx+b.

The correct option is A b−ak−mGiven equation is: kx+a=mx+b ⇒ kx–mx=b–a [mx is transposed as –mx, a is transposed as –a] ⇒ x(k–m)=b–a ⇒x=b−ak−m

Find the value of $x$ in $k x + a = m x + b$ .

The correct option is A $\frac{b - a}{k - m}$
Given equation is: $k x + a = m x + b$
$\Rightarrow$ $k x - m x = b - a$
[mx is transposed as –mx, a is transposed as –a]
$\Rightarrow$ $x (k - m) = b - a$
$\Rightarrow x = \frac{b - a}{k - m}$
