7x-3(9x+4)=9(-x-1)+x

7 x - 3 (9 x + 4) = 9 (- x - 1) + x

x = - \frac{1}{4}

Decimal Notation

x = - 0.25

Solution steps

7 x - 3 (9 x + 4) = 9 (- x - 1) + x

Expand

- 3 (9 x + 4) : - 27 x - 12

7 x - 27 x - 12 = 9 (- x - 1) + x

Add similar elements:

7 x - 27 x = - 20 x

- 20 x - 12 = 9 (- x - 1) + x

Expand

9 (- x - 1) + x : - 8 x - 9

- 20 x - 12 = - 8 x - 9

Move

12

to the right side

- 20 x = - 8 x + 3

Move

8 x

to the left side

- 12 x = 3

Divide both sides by

- 12

x = - \frac{1}{4}

- 3 k + 4 = - 2 - 6 k

2 (x + 4) = 8

m, 2 m = - 6 n - 5

\frac{x + 1}{4} - \frac{x - 1}{5} = 2

25 = 3 - \frac{2}{7} c
