Step-by-step explanation:
(h) x - 2y = -1 and 2x - y = 7
=>2x - 4y = -2 and 2x - y = 7
On subtracting both,
2x - 4y - 2x + y = - 5
=> - 3y = -5
=> y = 5/3
On putting y,
x - 2(5/3) = -1
=> x - 10/3 = - 1
=> x = 7/3
(i) Let Deepika' s age be x.
Then Priyanka's age = x + 6
=> x + x + 6 = 34
=> 2x = 28
=> x = 14
Therefore Deepika's age = 14 , Priyanka's age = 20
