-x/5 - x/6 = 7
LCM: 30
-x/5*6/6 = -6x/30
-x/6*5/5 = -5x/30
-6x/30 - 5x/30 = 7
-11x/30 = 7
-11x = 7*30
-11x = 210
x = 210/-11
x = -19.09
Hope it helps :)

Answer :
![- \frac{x}{5} - \frac{x}{6} = 7 \\ \\ lcm = 30 \\ \\ multiply \: both \: sides \: by \: 30 \\ \\ - 6x - 5x = 210 \\ \\ - 11x = 210 \\ \\ x = - \frac {210}{11} \\ \\ x = - 19.09091 - \frac{x}{5} - \frac{x}{6} = 7 \\ \\ lcm = 30 \\ \\ multiply \: both \: sides \: by \: 30 \\ \\ - 6x - 5x = 210 \\ \\ - 11x = 210 \\ \\ x = - \frac {210}{11} \\ \\ x = - 19.09091](https://tex.z-dn.net/?f=+-++%5Cfrac%7Bx%7D%7B5%7D++-++%5Cfrac%7Bx%7D%7B6%7D++%3D+7+%5C%5C++%5C%5C+lcm+%3D+30+%5C%5C++%5C%5C+multiply+%5C%3A+both+%5C%3A+sides+%5C%3A+by+%5C%3A+30+%5C%5C++%5C%5C++-+6x+-+5x+%3D+210+%5C%5C++%5C%5C++-+11x+%3D+210+%5C%5C++%5C%5C+x+%3D+++-+%5Cfrac+%7B210%7D%7B11%7D+++%5C%5C++%5C%5C+x+%3D++-+19.09091)
