Answer:
y = 6
Step-by-step explanation:
Perform the indicated multiplication: 6y + 12 = 8y
Consolidate y terms on the right: 12 = 8y - 6y = 2y, or y = 6
The fraction is 1/3. on the input side, it’s going up by one, (6,7,8 etc) and on the output side it’s going up by 3. (18+3=21). if u were to double check 6/18 reduces to 1/3! so the answer is 1/3
