3 x - 9 x + 6 = 20 - 3 x + 4 x

x = - 2

Solution steps

3 x - 9 x + 6 = 20 - 3 x + 4 x

Add similar elements:

3 x - 9 x = - 6 x

- 6 x + 6 = 20 - 3 x + 4 x

Add similar elements:

- 3 x + 4 x = x

- 6 x + 6 = 20 + x

Move

6

to the right side

- 6 x = x + 14

Move

x

to the left side

- 7 x = 14

Divide both sides by

- 7

x = - 2

1 0^{(\frac{3}{10})}

34 = 162 + 32 t - 16 t^{2}

9 x^{2} + 9 x + 2

z^{2} - 9 z + 20

2 > - 2
