Here the unknown variable which needs to be solved for is x.

First step: Adding 2 on both sides of the given equation.

(11 x – 2) + 2 = 20 + 2.

This gives 11 x = 22.

Now dividing both sided of the equation by 11.

This gives 5 x/ 5 = 30 / 5.

This reduces the given equation to x = 6.

Hence the solution is x = 6.

Here the unknown variable which needs to be solved for is x.

First step: Adding 3 on both sides of the given equation.

(4 x – 3) + 3 = 33 + 3.

This gives 4 x = 36.

Now dividing both sided of the equation by 4.

This gives 4 x/ 4 = 36 / 4.

This reduces the given equation to x = 9.

Hence the solution is x = 9.
