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
