Answer: 3y + 4

Step-by-step explanation:

Question:  3(y - 1) + 7    

▪︎ BODMAS, (Brackets, of Division, Multiplication, Addition, Subtraction), therefore brackets come first. 3 multiply Y; 3 multiply ( -1 )

3y - 3 + 7

▪︎Now we group numbers with numbers then numbers and letters with numbers and letters.

3y    (-3 + 7)

▪︎In this question, since the positive number is bigger than negative number the answer takes the positive sign. You can also use a number line and count seven steps to the right.
