If you are using an unknown value, use a variable and define whatit stands for.
Let Matt's weight be #w#

Look for the clues ...
#rarr# 'twice' means times by 2.
#rarr# 'sum' means add, It is used with AND, to tell you what to add together.

In this case, the main operation is addition.
Then that needs to be multiplied by 2

# ?? + ?? #

#27 + w" "larr # the sum of 27 and Matt's weight

#2(27+w)" "larr# twice the sum of 27 and Matt's weight
