Download 9th Class Math Exercise 5.4 Notes PDF – Word Problems on Linear Systems (FBISE 2025)

Exercise 5.4 transfers your simultaneous‑equation skills into realistic word problems involving ages, mixtures, cost/profit and motion. Many students freeze here because translating prose into equations feels like learning a new language. That’s why this PDF opens with a four‑step decoding template: identify variables, extract numerical data, set up equations, then solve. We link every template step to the FBISE marking scheme and illustrate it with authentic questions from BISE Lahore, BIE Karachi, BISE Sargodha and BISE Peshawar. Side‑by‑side solutions highlight where each board awards method marks. After ten fully‑worked questions, a practice bank of twenty problems is arranged by context. You can tackle just the “mixture” set if chemistry is your weak spot, or “age” problems before a quick test. A printable answer key (last page) lets you self‑mark.
