[tex]Jam's \ age \ now : \ \ x\\Dindo's \ age \ now : \ \ y\\Jam's \ age \ in \ 2 \ years : \ \ x+2 =y\\ Dindo's \ age \ in \ 26 \ years : \ \ y+26=2x\\\\\begin{cases} x+2 =y \\y+26=2x \end{cases}\\\\[/tex]

[tex]\begin{cases} x-y=-2 \\-2x+y=-26 \end{cases}\\----------\\ -x=-28\ \ / *(-1)\\x=28\\\\28+2=y\\y=30 \\\\Answer: \ Jam's \ age \ now : \ \ 28 \\Dindo's \ age \ now : \ \ 30[/tex]
