2/9s = -6

I'm having trouble with it :cry:

Also:

2x - 6/4 = -7

2/3g + 1/2g = 14

If you could explain it, that would be great :D

2/9s = -6 means \(\displaystyle \frac{2}{9}s = -6\) which you would solve by multiplying both sides of the equation by 9, then dividing both sides of the equation by 2.
However, if you mean 2/(9s) = -6 which is \(\displaystyle \frac{2}{9s} = -6\) then solve for s by multiplying both sides of the equation by 9s and then dividing both sides by the resulting coefficient of s.

Dany, 20/5*2 = 4 * 2 = 8
but 20/(5*2) = 20 / 10 = 2

The above could mean either of the following:

. . . . .\(\displaystyle \L \frac{2}{9s}\, =\, -6\)

. . . . .\(\displaystyle \L \frac{2}{9}s\, =\, -6\)

...and the solution method will vary, according to the type of equation you meant. Same goes for the other two equations.

Okay.... but how? We can't "see" where you're having trouble, if you don't know your work. So please reply showing everything you've tried so far. :!:

Please be complete. Thank you! :D
