let x be Mr. A's age and y be the age of Mr. A's father
:
1) y = x+27
:
2) 4(x+3) = y+3
:
use equation 1 to substitute for y in equation 2
:
4(x+3) = x+27+3
:
4x+12 = x+30
:
3x = 18
:
x = 6
:
***************************************************
Mr A's age is 6 and Mr. A's father's age is 6+27=33
:
check the answer with equation 2
:
4(6+3) = 33+3
:
36 = 36
:
answer checks
