<PRE><B>Question 253221</B>
By definition, a parallelogram has opposite side which are congruent. So,
(i) MR = TS
(ii) MT = SR.
the (y) and (x) are just variables that we need to solve the problem.
--
From (i) we get
(iii) 2y - 10 = y - 3 
--
From (ii) we get
(iv) 3x + 6 = 2x + 10.
--
Solve (iii) for y.
y = 7
--
Solve (iv) for x.
x = 4. 
--
So, 
from (i) we get MR = 2(7) - 10 = 4.
From (iii) we get MT = 3(6) + 6 = 24.
