Answers

Answer 1

Answer: $(3a+6):3+18=50 \n\n (3a+6):3=50-18 \n\n (3a+6):3=32 \n\n 3a+6=32*3 \n\n 3a+6=96 \n\n 3a=96-6 \n\n 3a=90 \n\n a=90:3 \n\n \boxed{a=30}$

Answer 2

Answer:

if 3xa=3 times a then
so the quantity (3xa+6) is divided by 3 so factor out the three and get3(a+2) divide by three and get (a+2)+18 and the associative propertyof addition allows us to move the parenthasees to (a+2+18)=50 or a+20=50 subtract 20 from both sides and get
a=30

or (3a+6)/3+18=50
3(a+2)/3+18=50
a+2+18=50
a+20=50
a=30
