代数の例題
以下の例題は現在、英語のみで提供されています。
1. Solve for x: 6x + 5 = -7+
答え: x = -2
Step 1: Subtract 5 from both sides: 6x = -12. Step 2: Divide both sides by 6: x = -2.
2. Solve for x: 4x + 20 = 16+
答え: x = -1
Step 1: Subtract 20 from both sides: 4x = -4. Step 2: Divide both sides by 4: x = -1.
3. Solve for x: 9x - 9 = 36+
答え: x = 5
Step 1: Add 9 to both sides: 9x = 45. Step 2: Divide both sides by 9: x = 5.
4. Solve for x: 8x - 7 = 65+
答え: x = 9
Step 1: Add 7 to both sides: 8x = 72. Step 2: Divide both sides by 8: x = 9.
5. Solve for x: 3x + 14 = 35+
答え: x = 7
Step 1: Subtract 14 from both sides: 3x = 21. Step 2: Divide both sides by 3: x = 7.
6. Solve for x: 2x + 1 = -15+
答え: x = -8
Step 1: Subtract 1 from both sides: 2x = -16. Step 2: Divide both sides by 2: x = -8.
