Let’s solve the equations below:

5x = 30

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

We have

5x = 30

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.

Note that, 5 is multiplied to x on L.H.S of the equation.

So, divide 5 on both sides of the equation so that we have x idle on L.H.S.

⇒ x = 6

Thus, we have solved the equation and x = 6.
