2. jiteshmeghwal9

i can't read it properly :(

3. jiteshmeghwal9

4. jiteshmeghwal9

can u plz write it through equation editor :)

5. thrustfault

Looks like $x-y=24$ $\frac{1}{2}x+3 = 20$

i dont know how to write the the mark underline the equation :(

7. thrustfault

Sorry, the second one should be 1/2x+3=120?

8. hartnn

eyad,u know the l shaped sign u made ,what does that mean??

@thrustfault :not only that ,with the underline mark

@hartnn :hmmm,I think it was fractional anyway i know some property may help anyone to recognize it : |dw:1344856830420:dw|

11. thrustfault

Floor brackets?

12. jiteshmeghwal9

x/2=20-3 x=(20-3)2 x=17/2

13. satellite73

ahh factorial notation?

14. hartnn

i knew what it meant...i just wanted to know if u did...

OR|dw:1344856909048:dw|

16. jiteshmeghwal9

put the value in the equation x - y=24 17/2-y=24

yea I think its @satellite73

18. satellite73

got it that is very nice notation. most people use $$n!$$

yea i use it in calculator through !

20. satellite73

and since i cannot typset it that way here, i will use $$n!$$

ok

22. hartnn

since (x-y)!=24....x-y=4 i converted that into linear equation....can u do the same thing for 2nd equation??

23. satellite73

$$5!=120$$ so $$\frac{1}{2}x+3=5$$ solve for $$x$$ you good from there ?

yes i got it Ty

25. jiteshmeghwal9

Ty=?

Thank you :)

27. satellite73

ok between my response and @hartnn answer you have two equations to solve, which you can just about do in your head right?
