Solve the following equations and check your results.
$ 3 x=2 x+18 $.

Given:

\( 3 x=2 x+18 \).

To do:
 We have to solve the given equation and check the result.

Solution:

$3x=2x+18$

$3x-2x=18$

$x=18$

Substituting the value of $x$ in LHS, we get,

$3x=3(18)$

$=54$

Substituting the value of $x$ in RHS, we get,

$2x+18=2(18)+18$

$=36+18$

$=54$

LHS $=$ RHS

The value of $x$ is $18$.
