9x-(5x+1)-{2+8x-(7x-5)}+9x=0

9 x - (5 x + 1) - {2 + 8 x - (7 x - 5)} + 9 x = 0

x = \frac{2}{3}

Decimal Notation

x = 0.66666 \dots

Solution steps

9 x - (5 x + 1) - {2 + 8 x - (7 x - 5)} + 9 x = 0

Group like terms

9 x + 9 x - (5 x + 1) - (8 x - (7 x - 5) + 2) = 0

Add similar elements:

9 x + 9 x = 18 x

18 x - (5 x + 1) - (8 x - (7 x - 5) + 2) = 0

Expand

18 x - (5 x + 1) - (8 x - (7 x - 5) + 2) : 12 x - 8

12 x - 8 = 0

Move

8

to the right side

12 x = 8

Divide both sides by

12

x = \frac{2}{3}

2 (x - 1) (x - 2) - 3 (x + 1) = (x - 4) (2 x - 3) + 1

y, x - y = 1

x, 4 x + 2 y = 0

x, 4 x + 4 y = 4

x, 4 x + 2 y = - 18
