Determine whether x=5 is the solution to -7+x=2.

Expert Answers

An illustration of the letter 'A' in a speech bubbles

To determine if x=5 is a solution, plug-in this to the equation.



`-2=2`      (False)

Since the resulting condition is False, hence x=5 is not the solution of `-7 + x = 2` .

To determine the solution of the given equation, move 7 to the right. To do so, add both sides by 7.




Hence, the solution of `-7+x=2` is `x=9` .
