The cost of three books are $4, $8 and $12.
The linear equations in one variable is an equation which is expressed in the form of ax + b = 0, where a and b are two integers, and x is a variable and has only one solution.
According to the given question
We have
Number of books purchased by Drew = 3
Total cost of the three books = $24
Cost of each book is multiple of 4.
Let the cost of three books be 4x, 8x and 12x.
So, we have
A linear equation in one variable
4x + 8x + 12x = 24
⇒ 24 x = 24
⇒ x = 1
Therefore, the cost of three books will be
4x = 4 × 1 = $4
8x = 8 × 1 = $8
12x = 12 × 1 = $12
