Question

What is the missing coefficient?

mc027-1.jpg = mc027-2.jpg
4
8
10
22

Answer 1

I can't see the image file you referenced. Could you either

- paste the full equation/text from the image, or
- attach or describe both sides (what each term is)?

If you want to try yourself, here are two quick methods depending on the problem type:

1) If it's an algebra/polynomial equation (e.g. ax + ... = ...):
- Expand both sides.
- Collect like terms (group x^2, x, constants).
- Equate coefficients of corresponding powers and solve for the missing coefficient.

2) If it's a chemical equation to balance:
- Count atoms of each element on both sides.
- Set up simple integer equations for the stoichiometric coefficients.
- Solve the small system (usually by inspection) and use the smallest whole-number coefficients.

Send the equation and I’ll find which choice (4, 8, 10, or 22) is correct.
