Answer:
-17/14
Step-by-step explanation:
To subtract fractions, you must have a common denominator. If that is not given, you make it.
You do so buy finding the LCM of denominators:
LCM of 7 and 2 = 14
Now, here you have multiplied the denominators either by 7 or 2. You do the same for the respective numerators:
2x2/14 - 3x7/14 = 4/14 - 21/14.
Now that you have the same denominator, subtract the numerators:
4-21 = - 17
Put it back as a fraction : -17/14

Answer:
He messed up on x + 2 = 5 (when he divided both sides by 3.)
He is first supposed to subtract 2 from both sides and you would get 13. Then you would divide both sides by 3 which would get you 4.33 repeating.
