If 2x - 13 = 5 then 2x = 5 + 13 (we have in effect added 13 to both sides of the equation in this step) 2x = 18 x = 9.

Yes
It is an equation and the value of x is 1.5
This is already the equation. Now you just have to solve it. x=5.
2x + 5 = 25 2x = 20x = 10
If 2x - 13 = 5 then 2x = 5 + 13 (we have in effect added 13 to both sides of the equation in this step) 2x = 18 x = 9.
It is a linear equation in x. The equation has the solution x = 0.

Yes
An equation where x = 3
It is an equation and the value of x is 1.5
This is already the equation. Now you just have to solve it. x=5.
2x must equal 12 so x is 6.
X=2
