If two equations are 3x + 2y = 14; 5x + 3y = 12, then the value of
5x – y is
1 answer:
Answer:
-124
Step-by-step explanation:
3x + 2y = 14 (×3) → 9x + 6y = 42
- → x = -18
5x + 3y = 12 (×2) → 10x + 6y = 24
3(-18) + 2y = 14
-54 + 2y = 14 → 2y = 14 + 54 = 68 → y = 68/2 = 34
5x - y = 5(-18) - 34 = -90 - 34 = -124
