It is given that Pamela is 12 years older than Jiri.
The sum of their ages is 82.
Let the Pamela age be x.
Jiri age be y.
Then the equation formed is
[tex]x=y+12[/tex][tex]x+y=82[/tex]Solve the above two equations and find x and y.
[tex]\begin{gathered} y+12+y=82 \\ 2y=82-12 \\ 2y=70 \\ y=35 \end{gathered}[/tex]Now find x,
[tex]\begin{gathered} x+35=82 \\ x=82-35 \\ x=47 \end{gathered}[/tex]Hence the Jiri's age is 35 years.
