Question

R1+r2 = 10
r1-r2 = 3
Bisa ga nyari kedua r kalo yg diketahui itu? Kalo bisa tolong caranya, makasih : )

Answer 1

Bisa bangettt :)
r1+r2 = 10
r1-r2 = 3
----------- - (dikurangi)
2 r2 = 7
r2 = 7/2 = 3,5
r1 = 3+r2 = 6,5

Answer 2

*R1 + R2 = 10
 R1 - R2 = 3          +
---------------------------
2R1      = 13
R1 = 13 / 2 = 6,5

*R1 + R2 = 10
6,5 + R2 = 10
R2 = 10 - 6,5 = 3,5
