Ответ:
Yes
Step-by-step explanation:
Reason 1: If you were to plug in a number for y, they both would come out as equal.
Ex: y=2,
7y + 5 - 3 = 7(2) + 5 - 3 = 14 + 5 -3 = 19 - 3= 16
7y + 2 = 7(2) + 2 = 14 + 2 = 16
Reason 2: 5 - 3 = 2
Ответ:
Yes, they are.
Step-by-step explanation: 7y + 5 - 3 could be solved by adding similar terms. So, in this case: 7y + 5 - 3 = 7y + 2. So, the expressions are equal.
