*Find the value of the variable and LM if L is between N and M
9) NL = 5x, LM = 3x, and NL = 15
*Find the value of the variable and ST if S is between R and T
28) RS = 7a, ST = 12a, RS = 28
how do you work these out?

9) If NL =5x and NL=15
then 5x=15 and you solve for x.
28) Same technique, you are given RS as 28 and 7a solve for a.
