|dw:1433534473361:dw| cross multiply ^^^example

3. Nnesha

|dw:1433534630452:dw| same like abcd example cross multiply

4. Jravenv

How do you cross multiply that though?

5. Nnesha

|dw:1433534866099:dw| like this and then distribute parentheses by 8

6. Nnesha

multiply $$\rm \color{green}{top}$$ of first fraction by the $$\rm \color{red}{bottom}$$ of the 2nd fraction and multiply bottom of the first fraction by the top of 2nd fraction

7. Jravenv

So like 8k+11?

8. Nnesha

|dw:1433535053525:dw| distribute: multiply everything which is inside the parentheses by outside term so 8(k+3) = 8 times k + 8 times 3

9. Jravenv

so 8k+24?

10. Nnesha

yes right now multiply top of first fraction by bottom of 2nd fraction

11. Jravenv

3k-9?

12. Nnesha

how did you get 9 @Jravenv
