Full solution

Q. (b) 5−3a−48+a2 5-\frac{3 a-4}{8}+\frac{a}{2}
  1. Find Common Denominator: Combine the terms with 'a' by finding a common denominator, which is 88. So, (a/2)(a/2) becomes (4a/8)(4a/8).
  2. Combine 'a' Terms: Now we have 5−3a−48+4a85 - \frac{3a - 4}{8} + \frac{4a}{8}. Combine the 'a' terms: −3a8+4a8-\frac{3a}{8} + \frac{4a}{8} equals a8\frac{a}{8}.
  3. Correct Mistake: Add this to 55, so we have 5+a85 + \frac{a}{8}. But wait, I made a mistake in the previous step, I should have subtracted (3a−4)/8(3a - 4)/8 from 55, not added it.
