jika 2a+1=64 dan 3b+1=27 , berapa nilai a+b

Materi : Penyederhanaan Linear
Tingkatan SMP

•2a + 1 = 64
= 2a = 64-1
= 2a = 63
= a = 63/2
= a = 63/2

•3b + 1 = 27
= 3b = 27 - 1
= 3b = 26
= b = 26/3

Yng di tanya adalah a + b sehingga :
a + b
= (63/2) + (26/3)
= 241/6 atau klo di sederhanakan = (40)1/6

2a + 1 = 64
2a= 64 - 1
2a = 63
a = 63/2


3b + 1 = 27
3b = 27 - 1
3b = 26
b = 26/3


a + b

63/2 + 26/3
189/6 + 52/6
241/6
40 1/6
