Question

3(2x-9+7/4=7.75
What is value of x

Answer 1

I assume you mean 3(2x − 9 + 7/4) = 7.75.

Steps:
- Combine constants: −9 + 7/4 = −29/4.
- 3(2x − 29/4) = 7.75 → 6x − 87/4 = 31/4.
- 6x = 118/4 = 59/2 → x = (59/2)/6 = 59/12 ≈ 4.9167.

If instead you meant 3(2x − 9) + 7/4 = 7.75, then x = 11/2 = 5.5.
