Harry can first substitute 30 for t
He can then multiply by 30 to get a product of 10
Since, 10 is not equal to 15, Harry's solution is not correct.
<em><u>Solution:</u></em>
Given that,
Harry solves the equation:
He says the solution is 30
We have to check if his answer is correct or not
<em><u>Fill in the blanks to explain how Harry can check whether his solution is correct</u></em>
Harry can first substitute 30 for t
He can then multiply by 30 to get a product of 10
Since, 10 is not equal to 15, Harry's solution is not correct
<em><u>Correct solution:</u></em>
Thus correct solution is 45
