Answer:
Harry can first substitute 30 for t. He can then multiply [tex]\frac{1}{3}[/tex] by 30 to get a product of 10. Since, 15 is not equal to 15, Harry's solution is not correct.
Step-by-step explanation:
Harry solves the equation [tex]\frac{1}{3}t = 15[/tex]. He says the solution is 30.
Now, to check whether Harry correct or not, Harry can first substitute 30 for t. He can then multiply [tex]\frac{1}{3}[/tex] by 30 to get a product of 10. Since, 15 is not equal to 15, Harry's solution is not correct.
This is an alternate way to check the answer obtained is correct or not. (Answer)
