Penjelasan dengan langkah-langkah:
AljabAr
x + a - b = 30
x - b = 20
a + b = 15
Y -a + x - y + b = ?
x + a - b = 30
x - b = 30 - a
x - b = 20
30 - a = 20
a = 30 - 20
a = 10
a + b = 15
10 + b = 15
b = 15-10
b = 5
x - b = 20
x - 5 = 20
x = 20 + 5
x = 25
Y - a + x - y + b
= 60 - 10 + 25 - 60 + 5
= -10 + 25 + 5
= -10 + 30
= 20
Hasil operasi Aljabar diatas adalah 20
