Explicación paso a paso: Comprobación
A) 6k-17 = 37 | K = 9
6k = 37+17 | 6(9) - 17 = 37
6k = 54 | 54-17 = 37
k = 54/6 |
k = 9 |
-------------------------------------------------------------------------------------------------------------
B) 25f-19 = 6 | f = 1
25f = 6+19 | 25(1)-19 = 6
25f = 25 | 25-19 = 6
f = 25/25 |
f = 1 |
-----------------------------------------------------------------------------------------------------------
C) 9n-25 = 65 | n = 10
9n = 65+25 |9(10)-25 = 65
9n = 90 |90-25 = 65
n = 90/9 |
n = 10 |
