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.`
