Answer:
6 23.2 40.4 57.6 74.8 92
Step-by-step explanation:
92-6 = 86
86/5 spaces = 17.2 each
While you cannot solve 946x+642y=911 for numerical values of x and y, you can indeed solve 946x+642y=911 first for x and then for y:
-911 - 642y
For x: 946x+642y=911 becomes 946x = 911 - 642y, or x = ------------------
946
911-946x
For y: 946x+642y=911 becomes 642y = 911-946x, or y = ---------------
642
I think the Answer is 64 !!!
