Answer:
Step-by-step explanation:
Let j and b represent Jera's and Bipu's current ages.
j-5 = (b +8) -20 . . . . . Jera's age 5 years ago was 20 less than Bipu's age in 8 years
b-5 = 2(j+8) -34 . . . . .Bipu's age 5 years ago was 34 less than Jera's age in 8 years
__
Solving the first equation for j gives ...
j = b + 8 -20 + 5
j = b -7
Using that in the second equation, we get ...
b -5 = 2((b -7)+8) -34
0 = b -27 . . . . . . . subtract (b-5) and simplify
b = 27
j = 27 -7 = 20
Jera is 20; Bipu is 27.
