Answer:
-5/8
Step-by-step explanation:
So basically with fractions that have different denominators you have to find the GCF (greatest common factor) of both of them, in this case 8 would be a GCF because it you times 4 and 2 you get a whole number of 8. since we found out the GCF we want to set them equal. so take the 1/4 and multiply both the top and bottom by 2, so we end with 2/8. You set the equation back up (-7/8) + (2/8). and combine the numerators -7+2/8 which ends you with with the answer of (-5/8) :)

Answer:
3/17
Step-by-step explanation:
-2x + 3(-5x + 1)
-2x -15x +3
-17x + 3
17x = 3
x = 3/17
Subtract 7, so the answer is x <= 3, or C.
