Altogether, they pay $1800 for the rent.

The first two people pay a combined total of 75% for the rent. That leaves Andrzej with 25% to pay and he paid 450.
So 450 is 25% or 1/4 of the rent.

450 x 4 = 1800 for the total rent

They pay altogether for the rent of £1800 as per linear equation.

What is a linear equation?

"A linear equation is an equation in which the highest power of the variable is always 1. It is also known as a one-degree equation. "

Let, they pay altogether for the rent of £x.

Therefore,  Charlie pays the rent of £[tex]\frac{x}{4}[/tex].

Mo pays the rent of £[tex]\frac{x}{2}[/tex].

Therefore, Andrzej pays the rent of £(x - [tex]\frac{x}{4}[/tex] - [tex]\frac{x}{2}[/tex]) = £[tex]\frac{x}{4}[/tex]

Now, £[tex]\frac{x}{4}[/tex] = £450

⇒ x = 4 × 450 = 1800

Therefore, they pay altogether for the rent of £1800.
