Answer:
ML=93
Step-by-step explanation: x+243 is the total length of the line. So you want to put x+243 on one side of the equation and everything else on the other side.
x+243=110+4x+x+103+70 combine like terms
x+243=283 +5x subtract 5x from both sides
-4x+243=283 subtract 243 from both sides to get x by its self
-4x=40 Divide both sides by -4
x= -10
Now fill in -10 anywhere there is an x to check
-10+243=110+(4* -10)+ -10+103+70 Simplify
233=110+ -40+ 163
233=233
Since it is correct you now know that ML= -10+103
ML=93
