What are linear equation?

A linear equation only has one or two variables. No variables in a linear equation is raised to power greater than 1 or used as denominator of a fraction.

Now it is given that,9 more than twice a number is 3 less than three times the same number.

Let the number be x.

So, 9 more than twice a number = 9 +2x

and, 3 less than three times the same number = 3x - 3

Hence we have,

9 + 2x = 3x - 3

Adding 3 both the side we get,

12 + 2x = 3x

Now substracting 2x both the side we get,

x = 12

Hence the number is 12.
