-5 from both sides as it’s the way to get the x on one side and the numbers on the other

2x=20 is 10

As to get rid of x, you have to divide 2 as it’s technically saying 2*x=20
Let’s start by rewriting the equation:

2x + 5 = 25

We need to isolate the variable now. To do so, we have to get rid of the 5. The inverse operation of addition is subtraction, so we would subtract 5 from both sides:

2x + (5 - 5) = 25 - 5

Now let’s simplify to make it easier:

2x = 20

Given 2 is a coefficient, we divide both sides by 2 so that x is by itself:

2x / 2 = x

20 / 2 = 10

That leaves us with our answer:

x = 10
