# x+4=6  what is the value of x

Solve for x.

`x + 4 = 6`

In order to solve for x you must isolate the variable.  In order to isolate the variable, you must undo the operations.

Subtract 4 from each side.

`x + 4 - 4 = 6 - 4`

`x + 0 = 2`

`x = 2`

The solution is x = 2.

You need to solve for `x` the linear equation, hence, you need to isolate the unknown x to the left side, subtracting 4 both sides, such that:

`x + 4 = 6 => x + 4 - 4 = 6 - 4`

Reducing duplicate terms, yields:

`x = 2`

Hence, evaluating the solution to the given one step equation, yields `x = 2.`
