(i) 3y – 1 = 26 [In a parallelogram opposite sides are of equal length]
3y = 26 + 1
Y = \(\frac{27}{3}\) = 9
Y = 9 units
3x = 18 [In a parallelogram opposite sides are of equal length]
x = \(\frac{18}{3}\) = 6
x = 6 units
(ii) y – 7 = 20 [In a parallelogram diagonals bisect each other]
y = 20 + 7
Y = 27 units
x - y = 16 [In a parallelogram diagonals bisect each other]
x - 27 = 16
x = 16 + 27 = 43 units
