Answer:
1/2
Step-by-step explanation:
(6/8)-(2/8)=(4/8)
(4/8) = 1/2
You will divide the 12 by 28: 12/28 and that equals 3/7
Answer:
x1=3. x2=-2
Step-by-step explanation:

b=-1
a=1
c=-6





x1=3
x2=-2

We can treat this problem like you regularly subtract fractions. First find the common denominator, which is 15.
So:
5(x+6)/15 = 30/15 + 3(x-2)/15
(5x+6)/15 - (30/15) - (3x - 6)/15
As you already know the answer, I'm assuming you can do the rest.
Hope this helps!
