just need help on the following problem and dont understand it at all

"Suppose M is betweenL and N. Use the Segment Addition Postulate to solve for the variable. Then find the lenghts of segments LM, MN, and LN."

#32. LM = 7y+9
MN = 3y+4
LN = 143

thanks for the help

#32. LM = 7y+9
MN = 3y+4
LN = 143
You have LM + MN = LN ==> (7y+9) + (3y+4) = 143
