3 x=15 Can you explain to me, please.

Solution:

In Algebra, the equation is an expression which has  “equal to” sign. We need to solve for the variables in a given equation.

In the current problem, We are given the equation as 3x =15We observe that there is a variable  “x” is and there is a number “3′ which is multiplying the variable  “x”.In order to solve for the variable “x”, we do the reverse operation of multiplication which is division.

On dividing with 3  both sides, we get the expression as (3x/3) = 15 /3.
Hence the value of the variable x, which satisfies the given equation is
x =5.
