Question 1078596: Write a two-column proof for the following information.
Given: M is the midpoint of CD; CM = 5x – 2; MD = 3x + 2
Prove: x = 2
Answer by Boreal(15235) (Show Source): You can put this solution on YOUR website!
CM=md, because the midpoint of a line divides it into two equal segments.
5x-2=3x+2, substitution.
+2-2=0 additive inverse
5x+2-2=3x+2+2 properties of equations
5x=3x+4
-3x+3x=0 additive inverse
5x-3x=3x-3x+2+2
2x=4
x=2
