Question

3x-1/5-2/9x=124/5how do you solve this?

Answer 1

So first you would combine the like-terms so you get:
$\frac{7}{9} x - \frac{1}{5} = 124 \div 5$
and combine the second like-terms:
$\frac{7}{9}x - \frac{1}{5} = 24.8$
now you only have a two step equation and you continue by doing the reciprocal and you add the -1/5 to the 24.8 where you get:

7/9x=24.6

then because the 7/9 is being multiplied by the x and your trying to isolate it you divide it by the 7/9 on both sides and you'll end up getting

x=31.628571429....
