#x=-3#

Explanation:

Solve:

#10x+11=-19#

We want to get #x# on one side.

Subtract #11# from both sides.

#10x+11-11=-19-11#

Simplify.

#10x+0=-30#

#10x=-30#

Divide both sides by #10#. Cancel #10# on the left-hand side.

#color(red)cancel(color(black)(10))^1/color(red)cancel(color(black)(10))^1x=-30/10#

Simplify.

#x=-3#
