Answer:
A
Step-by-step explanation:
5 and 7 are both common factors of 35 and 40
Looking at the options you can eliminate C and D right away because 7 times 8 = 56 and not 40 like the problem is asking.
This leaves A and B. Looking at the equation the difference between the two are the + and -
Using the original equation (35x-40) as reference we see that it subtracts the two variables. Therefore leaving A as the answer
Exact form is x = 86/11
Mixed number form is x = 7 whole number 9/11
