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.

This is already the equation. Now you just have to solve it. x=5.
Yes
It is an equation and the value of x is 1.5
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.

2x+2=12
x^3=2x+5 x^3-2x-5=0 Graph the equation or use a calculator. x= 2.09455148

An equation where x = 3
2x must equal 12 so x is 6.
