Question 1058736
Let T be Tahir's age and M be Masud's age
:
1) T + M = 18
:
2) (T-3) = 3 * (M-3)
:
solve equation 1) for T
:
T = 18 - M
:
substitute for T in equation 2)
:
18 - M - 3 = 3M - 9
:
add M to both sides of =
:
15 = 4M - 9
:
add 9 to both sides of =
:
4M = 24
:
M = 6
:
From equation 1) T = 18 - 6 = 12
