ibu = b
anak = a
4 + b = 3 (a + 4)
4 + b = 3a + 12
b = 3a + 8
b - 6 = 24 + a
b = 24 + a
3a + 8 = 24 + a
2a = 16
a = 8
maka umur anak sekarang adalah 8 tahun
dan Anak = A
I + 4 = 3(A+4)
== I + 4 = 3A + 12
I = 3A + 8
I - 6 = 24 + (A - 6)
== I = 24 + A
Maka
24 + A = 3A + 8
3A - A = 24 - 8
A = 16 : 2
A = 8
jadi usia anak saat ini = 8 tahun
