Question

$x=3$ is the solution of the equation $x+3=0$.

• A. True
• B. False

Answer 1

The correct option is B

False

The value of unknown variable which satisfies the equation is called solution of the equation.

So, substituting $x=3$, we get $3+3$ i.e. $6$ which is not equal to zero. So, $3$ is not the solution of the equation.
