See a solution process below:

Explanation:

Step 1) Add color(red)(5) to each side of the equation to isolate the x term while keeping the equation balanced:

2x - 5 + color(red)(5) = -5 + color(red)(5)

2x - 0 = 0

2x = 0

Step 2) Divide each side of the equation by color(red)(2) to solve for x while keeping the equation balanced:

(2x)/color(red)(2) = 0/color(red)(2)

(color(red)(cancel(color(black)(2)))x)/cancel(color(red)(2)) = 0

x = 0

This is relatively a simple problem; since the constant (the number) can be cancelled out.

Explanation:

The simplest way is to solve for x:
which enables you to use the zero property of multiplication; if 3x = 0; x = 0

2x - 5=-5
2x = 0
x = 0
