Answer:

#x=-7#

See the process in the explanation.

Explanation:

Solve:

#6x-16=68+18x#

Subtract #6x# from both sides.

#color(red)cancel(color(black)(6x))-color(red)cancel(color(black)(6x))-16=68+18x-6x#

Simplify.

#-16=68+12x#

Subtract #68# from both sides.

#-16-68=color(red)cancel(color(black)(68))-color(red)cancel(color(black)(68))+12x#

Simplify.

#-84=12x#

Divide both sides by #12#.

#color(red)cancel(color(black)(-84))^(-7)/color(red)cancel(color(black)(12^1))=color(red)cancel(color(black)(12)color(black)x)/color(red)cancel(color(black)(12))#

Simplify.

#-7=x#

Switch sides.

#x=-7#
