a) (x + 3)/x = 6/4 |*4x |
4(x + 3) = 6x |
4x + 12 = 6x |-4x |
12 = 2x |:2 |
x = 6 |
|
b) (5 + x)/x = 12,5/8 |
8(5 + x) = 12,5x |
40 + 8x = 12,5x |
40 = 4,5x |
x = 8,9 (gerundet) |
|
c) (32 + 198)/198 = 238/x |
230x = 47124 |
204,9 (gerundet) |
|
d) 196,8/x = 96,8/(96,8 - 52,7) |
196,8/x = 96,8/44,1 |
8678,88 = 96,8x |
x = 89,7 (gerundet) |
