let g be gopinaths age and s be sons age
g= s + 30
g- s = 30. **eqn i
g = 2s + 11
g- 2s = 11. **eqn ii
eqn i - eqn ii:
s = 19
Substituting in eqn i:
g - 19 = 30
g = 30 + 19
= 49
Gopinath is 49 yrs old
son is 19 yrs old
g= s + 30
g- s = 30. **eqn i
g = 2s + 11
g- 2s = 11. **eqn ii
eqn i - eqn ii:
s = 19
Substituting in eqn i:
g - 19 = 30
g = 30 + 19
= 49
Gopinath is 49 yrs old
son is 19 yrs old
