This can be more illustrated in scope clarity by taking suitable examples. The examples are as follows:-

x

We know that,

16 = 4 * 4 = 4

Now by comparing equation no. 1 and equation no. 2, so we will get the following:-

x

That is x

So by comparing, we find that x =4

So x = 4 is the answer to the above problem

To find: - the value of unknown variable x

From given equation, 2x+3 = 10 ------ equation 1

In equation 1, to find the value of x, subtract 3 both sides, we will get

2x + 3 - 3 = 10-3

2x = 7

Now the last step to check the value of x is, we need to divide both sides by 2, we will get

2x/2 = 7/2

x = 7/2 = 3.5

Therefore, x = 3.5 is the solution.
