Moe is 12 years older than barney .three years ago ,moe was five times as old as barney .how old is barney now

M=12+b

m-3=5(b-3)
sub 12+b for m
12+b-3=5(b-3)
expand and combine like terms
b+9=5b-15
minus 4b both sides
9=4b-15
add 15 both sidse
24=4b
divide by 4
6=b

barney is 6
moe is 18
 3 years ago, barney is 3 and moe is 15, 3*5=15

barney is 6 now
