To divide mixed number, convert to improper fractions and divide them
(a/b)/(c/d)=(a/b)(c/d)=(ac)/(bd)
to multiply fractions, multily top by top and bottom by bottom
(a/b)(c/d)=(a times c)/(b times d)
Answer:
-8
Step-by-step explanation:
If 3x-4y=2, then for any number a we also have a(3x-4y)=a(2) by multiplication property of equality.
Therefore, for a=-4 we have -4(3x-4y)=-4(2) which means the value of -4(3x-4y) is -8.
