#x=-7/2#

Explanation:

#-2-6x=19#

Add #2# on each side of the equation to get rid of the #-2# on the left-hand side (whatever you do to one side of the equation, you must do to the other side)

#-2+2-6x=19+2#

#0-6x=19+2#

#-6x=21#

To solve for #x#, we must get #x# by itself. So, divide both sides of the equation by #-6#

#(-6x)/-6=21/-6#

#x=-21/6#

Simplify as much as possible, in this case, #3# is common in the denominator and numerator

#x=-7/2#
