j = # of jars
b = # of buckets
y = total # of rocks
2j + 3b = y (2 rocks per jar, 3 rocks per bucket)
Because Joy has 3 jars you can plug 3 in for "j", and because she has 4 buckets you can plug in 4 for "b"
2(3) + 3(4) = y
6 + 12 = y
18 = y
6 times y. one way to do these is read it out loud, and if that doesn't help than try explaining what the expression says, out loud. so you would read this as "six y", or you could explain it as 6y is saying you have y six times
5+6=11
11+6=17
17+6=23
x=6
2+4=6
6+4=10
10+4=14
y=4
6÷4= 1.5
1.5 as a fraction is 3/2
ANSWER= 3/2
