Step-by-step explanation:
In rectangle opposite sides are equal
2x + 20 = 6y - 6
2x - 6y = -6 -20
2x - 6y = -26 (i)
6y = 3x + 21 (ii)
Put 6y value in equation (i)
2x - (3x + 21) = -26
2x - 3x - 21 = -26
-x - 21 = -26
-x = -26 + 21
-x = -5
x =5
Put x = 5 in (ii)
6y = 3*5 + 21
6y = 15 +21
6y = 36
y = 36/6
y =6
Check:
6y - 6 = 6*6 - 6 = 36 - 6= 30
2x + 20 = 2*5 + 20 = 10+20 = 30
Opposite sides are equal
