Final answer:
To solve for [h] in the equation 3h = 7(2/7 - 3/7h) - 10, distribute the 7 to both terms inside the parentheses, simplify the fractions, combine like terms, and multiply both sides by the reciprocal to isolate [h]. The solution is h = -63/168.
Step-by-step explanation:
To solve for [h] in the equation 3h = 7(2/7 - 3/7h) - 10, we can follow these steps:
- Distribute the 7 to both terms inside the parentheses:
- 3h = 7(2/7) - 7(3/7h) - 10
- Simplify the fractions:
- 3h = 1 - 3/7h - 10
- Combine like terms:
- 3h + 3/7h = 1 - 10
- 24/7h = -9
- Multiply both sides by 7/24 to isolate [h]:
- 7/24 * 24/7h = -9 * 7/24
- h = -rac{9}{24} * rac{7}{7}
- [h] = -rac{63}{168}
