Answer:
19y+5
Step-by-step explanation:
Combine like terms look for all the numbers that have y attached and combine them
7y +12y=19y
Look for terms where nothing is attached it's just the number combine them
6-1=5
Put all together again and you get:
19y+5
I think the answer to 14 is J
Find 10% of it (just move the decimal point one spot to the left) and multiply by 4
