Solve

25 x + 450 \leq 3000

Solution:

Concept:

A linear inequality is solved like an equation. Keep the inequality sign, and isolate

x

by performing inverse operations.

Explanation:

Start with the given inequality:

25x + 450 \leq 3000

Subtract

450

from both sides to remove the constant:

25x \leq 3000 - 450

This simplifies to:

25x \leq 2550

Now divide both sides by

25

, the coefficient of

x

\frac{25x}{25} \leq \frac{2550}{25}

Since

25

is positive, the inequality sign remains unchanged:

x \leq 102

Answer:

x \leq 102
