Answer:
Step-by-step explanation:
- In order to combine these two equations, an idea you need to keep in mind is finding a way of setting these equations as equal to each other. I saw that each equation shared a common value, . In this case, we need to isolate in the first equation so that both equations .
- With this, we now know that both and are equal to , so we can set them equal to each other.
- Reply to this if anything I'm saying or doing is confusing in any way, or if you find a mistake. :) Solve for .
- Hopefully this answer is correct AND makes sense in terms of how I achieved it. Again, reply to this with any questions or mistakes I made and I'll do my best to answer or fix them.
