Answer:
x = 12
Explanation:
Solve for x:
-1/3 = 8/x - 1
-1/3 = 8/x - 1 is equivalent to 8/x - 1 = -1/3:
8/x - 1 = -1/3
Bring 8/x - 1 together using the common denominator x:
(8 - x)/x = -1/3
Cross multiply:
3 (8 - x) = -x
Expand out terms of the left hand side:
24 - 3 x = -x
Subtract 24 - x from both sides:
-2 x = -24
Divide both sides by -2:
Answer: x = 12
