Step-by-Step Solution
Key Concept: Multiply by 10: $4x + 3y = 17$ and $7x - 2y = 8$.
Multiply by 10: (1) $4x + 3y = 17$, (2) $7x - 2y = 8$. [0.5 Mark]
Multiply (1) by 2 and (2) by 3: $8x + 6y = 34$ and $21x - 6y = 24$. Add: $29x = 58 \Rightarrow x = 2$. [1.0 Mark]
$4(2) + 3y = 17 \Rightarrow 3y = 9 \Rightarrow y = 3$. Solution: $x = 2, y = 3$. [0.5 Mark]
