Question

Yang tau bantu jawab dongg, dikumpulin bsk!, yg A dan B yaa, pake caranya, lks matematika kls 9

Answer 1

A / 6 = a + 2 / 9
A. 9a = 6a + 12
9a - 6a = 12
3a = 12
a = 12 /3
a = 4

8 / b = a / 2
8 / b = 4 / 2
4b = 16
b = 16 / 4
b = 4

B. a / a + 8 = 6 / 10
10a = 6a + 48
10a - 6a = 48
4a = 48
a = 48 / 4
a = 12

6 / 10 = 9 / b
6b = 90
b = 90 / 6
b = 15
