Where are you stuck? It is rather hard to read your handwriting, so could we have the original problem from the book?

… with question 12(b) … I couldn’t [finish] …

Hi Anakbulan. You did good work on part 12(a).

Your beginning work on part 12(b) looks good, also. You've developed a system of two equations, to solve for h and k.

4h = 2k

3h = 6 - 6k

You then started what looks like the 'substitution method', by solving the first equation for k. You wrote k = (4/2)h, but then stopped.

Here are the next three steps.

(1) Simplify your expression for k:

k = 2h

(2) Substitute the expression 2h for k in the second equation:

3h = 6 - 6(2h)

(3) Solve for h

Once you know h, you can calculate k. Thanks for showing your work.
