-8.1(2x-2)-x=-10x+0.9(-10x+9)

- 8.1 (2 x - 2) - x = - 10 x + 0.9 (- 10 x + 9)

x = - \frac{9}{2}

Decimal Notation

x = - 4.5

Solution steps

- 8.1 (2 x - 2) - x = - 10 x + 0.9 (- 10 x + 9)

Multiply both sides by

10

- 81 (2 x - 2) - 10 x = - 100 x + 9 (- 10 x + 9)

Expand

9 (- 10 x + 9) : - 90 x + 81

- 172 x + 162 = - 100 x - 90 x + 81

Add similar elements:

- 100 x - 90 x = - 190 x

- 172 x + 162 = - 190 x + 81

Expand

- 81 (2 x - 2) - 10 x : - 172 x + 162

- 172 x + 162 = - 190 x + 81

Move

162

to the right side

- 172 x = - 190 x - 81

Move

190 x

to the left side

18 x = - 81

Divide both sides by

18

x = - \frac{9}{2}

19 = 1 - 5 x - 4 x

2 x = \frac{6}{7}

\frac{x + 2}{5} = 12

\frac{4}{9} (y + 3) = g

6 x - 3 = 2 x + 9
