Question

-x/5-x/6 = 7 then x =

Answer 1

-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 2

Answer :


$- \frac{x}{5} - \frac{x}{6} = 7 \\ \\ lcm = 30 \\ \\ multiply \: both \: sides \: by \: 30 \\ \\ - 6x - 5x = 210 \\ \\ - 11x = 210 \\ \\ x = - \frac {210}{11} \\ \\ x = - 19.09091$


Hope it would help you
