if c=a/b-d-e/f-d,find the value of f when a=3,b=4 c=-6,d=-5,e=2
Answers
Step-by-step explanation:
f={8/67} (decimal: .119403 to 6d. p)
PREMISES
The cardinal value of “f” in the equation c=a/b-d-e/f-d, where a=3, b=4 c=-6, d=-5, and e=2
CALCULATIONS
For the equation c=a/b-d-e/f-d, the cardinal value of the independent variable “f” can be calculated by deduction, where a=3, b=4, c=-6, d=-5, and e=2
Hence,
The mathematical proposition c=a/b-d-e/f-d becomes
-6=3/4-(-5)-2/f-(-5)
-6=3/4+5–2/f+5
-6–5–5=3/4+(5–5)-2/f+(5–5)
-16=3/4+0–2/f+0
-16=3/4–2/f
-16–3/4=(3/4–3/4)-2/f
(-16 3/4)=0–2/f
(-16 3/4)=-2/f (Eliminate the fractions by multiplying both sides of the equation by the least common denominator 4×f=4f)
4f[(-16 3/4)=-2/f]
4f[-67/4=-2/f]
-67f=-8
-67f/-67=-8/-67
f=
8/67 as a proper fraction (decimal: .119403 to 6d. p)
PROOF
If f=8/67, then the equations
c=3/4-(-5)-2/f-(-5)
-6=3/4+5–2/(8/67)+5
-6=(3/4+5+5)-2(67/8)
-6=(10 3/4)-2(67/8)
-6=43/4–67/4
-6=(43–67)/4
-6=-24/4 and
-6=-6 establish the root (zero) f=8/67 of the mathematical proposition -6=3/4-(-5)-2/f-(-5)

Answer:
Step-by-step explanation:
It looks to me that the question is
if c=a/(b-d)-e/(f-d)
In case this is the actual problem,
-6=3/( 4+5) - 2/(f+5)
simplification will give:
f+5=6/19 and f=-5+6/19 or -89/19
