8x+(-5x-9)=3x+[-5x-(x+3)]

8 x + (- 5 x - 9) = 3 x + [- 5 x - (x + 3)]

x = 1

Solution steps

8 x + (- 5 x - 9) = 3 x + [- 5 x - (x + 3)]

Remove parentheses:

(- a) = - a

8 x - 5 x - 9 = 3 x + [- 5 x - (x + 3)]

Add similar elements:

8 x - 5 x = 3 x

3 x - 9 = 3 x + [- 5 x - (x + 3)]

Remove parentheses:

(- a) = - a

3 x - 9 = 3 x - 5 x - (x + 3)

Add similar elements:

3 x - 5 x = - 2 x

3 x - 9 = - 2 x - (x + 3)

Expand

- 2 x - (x + 3) : - 3 x - 3

3 x - 9 = - 3 x - 3

Move

9

to the right side

3 x = - 3 x + 6

Move

3 x

to the left side

6 x = 6

Divide both sides by

6

x = 1

x^{2} - x + 7 = 0

x^{2} - 4 x = 2

8 + y < 1

3 (6 x - 10) - 5 (2 - 4 x) = 25 x - 1

6 x^{2} - 9 x - 6
