Question

plz help me with this​

Answer 1

Answer:

Leeta's Age = 42

Daughter's Age = 12

Step-by-step explanation:

Let Leeta's present age be "x" and

Her daughter's age be "y".

According to the Q,

>> (x - 7) = 7(y - 7) -----(1)

>> (x + 3) = 3(y + 3) -----(2)

(1) => x - 7 = 7y - 49

>> x - 7y = -49 + 7

>> x - 7y = -42 -----(3)

(2) => x + 3 = 3y + 9

>> x - 3y = 9 - 3

>> x - 3y = 6 -----(4)

(4) - (3) =>

>> -3y + 7y = 6 + 42

>> 4y = 48

>> y = 48/4

>> y = 12

Substitute in -----(4)

>> x - 3 * 12 = 6

>> x - 36 = 6

>> x = 6 + 36

>> x = 42
