Question 938520: M is the mid point of
LN .
If MN = x + 1 and LN = 3x + 1, what is LN?

You can put this solution on YOUR website!

if M is the mid point of LN .
and if MN+=+x+%2B+1 and LN+=+3x+%2B+1,
LN=2%2AMN
3x+%2B+1=2%2A%28x+%2B+1%29
3x+%2B+1=2x+%2B+2
3x-2x=+2-1
x=+1
so, LN+=+3%2A1+%2B+1=>LN+=+4
and MN+=+1+%2B+1=> MN+=+2
