Which equation represents the situation?
<u>Solution:</u>
Let smaller number =
According to Sam's description of the two numbers, the equation will be:-
Larger number = 3 more than three times the smaller number
=
According to Kim's description of the two numbers was, the equation will be:-
Larger number = Five times decreased by 7
=
By equating both equation:-
Smaller number = = 5
Larger number =
Therefore, equations represents the situation are and
