<PRE><B>Question 269601</B>
Let x be the length of the common side. Then, the length of the third side is 2x-2 because it is 2 meters less than twice the common side. Therefore you get
x+x+(2x-2)=22
2x+2x-2=22
4x=24
x=6
Then, by substitution
2(6)-2=?
12-2=10
Thus, the length of the common side is 6 and the length of the third side is 10.
CHECK:
6+6+10=22(?)
22=22 True</PRE>
