Question

State which of the following are equation? Also identify linear equation and justify your answer.

$\text{x - 12 + 2=-12}$.

Answer 1

Equations is an equality that involves one or more unknown values and an equation with variable of power $\text{1}$ is called linear equation.

$\text{x - 12 +2 = -12}$ is Linear equation

As there is $=$sign between L.H.S and R.H.S.

And degree of variable $x$ is $1$

Hence $\text{x - 12 +2 = -12}$ is a linear equation.
