(3x-20)/2 =-4

\frac{3 x - 20}{2} = - 4

x = 4

Solution steps

\frac{3 x - 20}{2} = - 4

Multiply both sides by

2

3 x - 20 = - 8

Move

20

to the right side

3 x = 12

Divide both sides by

3

x = 4

\frac{12 x ( x ^{3} - 2 )}{( x ^{3} + 1 ) ^{3}} \leq 0

f = 4 (3.9822) - (3.9822)^{2}

3 x^{2} - 42 = 0

x^{2} - 16 + 64

- 3 - 2 x > 9
