Given that f(x) = 2x - 5, find the value of x that makes f(x) = 15.

Solution:

Linear equations are nothing but yet another subset of "equations". Any linear calculations requiring more than one variable can be done with the help of linear equations. 

The standard form of a linear equation in one variable is of the form ax + b = 0. Here, x is a variable, and a and b are constants. 

The given function is a linear function whose degree is 1.

It is given that

f(x) = 2x - 5

We have to determine the value of x when f(x) = 15

15 = 2x - 5

We can write it as

2x = 15 + 5

By addition, we get

2x = 20

Dividing both sides by 2,

x = 10

Therefore, the value of x is 10.

Summary:

Given that f(x) = 2x - 5, the value of x that makes f(x) = 15 is 10.
