Answer
x+5=x-9
No solution for all x considered
Work Step by Step
An equation remains the same when same number is added/subtracted from both sides of the equation.
Consider equation x+5=x-9. Subtract x from left hand side and right hand side expressions, and simplify.
x+5-x=x-9-x
5=9
The statement 5=9 is not true. It indicates that there exists no value for x at which solution exist.
