Explanation:
1. Multiply both sides of the equation by 3 to get rid of the denominator in -x/3.
#-x/3-5=2x#
#3(-x/3-5)=3(2x)#
#-x-15=6x#
2. Bring 15 to the other side of the equation.
#-x-15# #color(red)(+15)=6x# #color(red)(+15)#
3. Simplify.
#-x=6x+15#
4. Bring 6x to the other side of the equation.
#-x# #color(red)(-6x)=6x# #color(red)(-6x)+15#
5. Simplify.
#-7x=15#
6. Divide -7 from both sides.
#-7xcolor(red)(-:-7)=15color(red)(-:-7)#
7. Simplify.
#color(green)(x=-15/7)#
