First multiply each term by 24(the common denominator found by 8×3) to remove the fractions and make things easier.
24(5) + 24( \frac{x - 2}{3} ) = 24( \frac{x + 3}{8} )
This will give you,
120 + 8(x - 2) = 3(x + 3)
Then just continue to simplify and isolate the variable.
120 + 8x - 16 = 3x + 9
8x + 104 = 3x + 9
5x =  - 95
x =  - 19

During the 2005-2006 term. 184 decisions were announced. This is a 44.6% decrease
Artyom0805 [142]

Answer:

332.

Step-by-step explanation:

Let the number of decisions made in 1982-1983 be x.

44.6% = 0.446.

This is a decrease,  so the number of decisions announced in 2005-2006 is

(1 - 0.446) * x and this =  184.

0.554x = 184

x = 184/0.554

x = 332.
