4x-5x+9=5x-9

4 x - 5 x + 9 = 5 x - 9

x = 3

Solution steps

4 x - 5 x + 9 = 5 x - 9

Add similar elements:

4 x - 5 x = - x

- x + 9 = 5 x - 9

Move

9

to the right side

- x = 5 x - 18

Move

5 x

to the left side

- 6 x = - 18

Divide both sides by

- 6

x = 3

\frac{- 1}{2 ( - 4 + 2 x )} = - 6 - 4 x

x^{5} - 3 x^{4} - 12 x^{3} + 30 x^{2} + 20 x - 48

- (4 - x) = \frac{3}{4} (x - 6)

\frac{25}{64}
