Y=(8)/(3-x) solve for x. The 8 is over 3-x, it is a fraction.
chubhunter [2.5K]

Answer:

x = -(8 - 3 y)/y

Step-by-step explanation:

Solve for x:

y = 8/(3 - x)

y = 8/(3 - x) is equivalent to 8/(3 - x) = y:

8/(3 - x) = y

Take the reciprocal of both sides:

(3 - x)/8 = 1/y

Multiply both sides by 8:

3 - x = 8/y

Subtract 3 from both sides:

-x = (8 - 3 y)/y

Multiply both sides by -1:

Answer:  x = -(8 - 3 y)/y

How can exponential and logarithmic functions be combined?
OLEGan [10]
It really depends on the question and what you want to solve. An exponential function can be written as y = x^2 and if you are solving for y then it will be log(base x) y = 2.

More Examples:
3x = 15
(log both sides with base of 3)
log(3)3x = log(3)15
since log(3)3 = 1 then,
(1)x = log(3)15
x = log 15 / log 3
= 2.465
