Let’s solve the equations below:

This is an algebraic equation which is univariate as it contains only one variable, that is, x.

We have

We need to solve this equation.

That is, we need to find the value of variable x.

We will use any kind of mathematical operation (addition, subtraction, multiplication or division) in order to find x.

Here,

Shift the constant � from L.H.S to R.H.S, it’s positive sign will become negative.

Multiply by 4 on both sides so that x can be left idle.

⇒ x = 0

Thus, we have solved the equation and x = 0.
