define the 3 numbers
smallest number = x
middle number = x + 2 
largest number = x + 4 
write the equation 
sum of the smallest number and twice the middle number 

20 more than the largest number 

equal the expressions

Break it down
"15 less than " means -15
"a number" means unknown or placeholder means x
"is equal to" means '='
'12' means 12
-15+x=12
add 15
x=27
