## anonymous one year ago help solving this 9x / 4 + 8 = 21

1. Kailee1423

Are you trying to solve for x?

2. anonymous

3. anonymous

would i multiply 4 on each side first?

4. Kailee1423

I honestly don't know where to start. Lol Is the beginning 9x divided by 4?

how did you get the 36?

7. anonymous

this doesn't look right

8. anonymous

If you multiply the four you get rid of the fraction.

9. anonymous

$\frac{ 9x }{ 4 } \div 8 = 21$

10. anonymous

sorry i wasnt specific enough

11. anonymous

i got 8.4

12. anonymous

yeah that's what i got at first, but if you subtract 8 first, you get 5.75

13. anonymous

you don't subtract first

14. anonymous

oh wait so you would follow PEMDAS right ?

15. anonymous

If you're dividing by 8, you can't subtract by 8.

$$\color{#0cbb34}{\text{Originally Posted by}}$$ @highschoolstuent55236 $\frac{ 9x }{ 4 } \div 8 = 21$ $$\color{#0cbb34}{\text{End of Quote}}$$ Are you dividing by 8 in your question or adding?
