9x-2.5(x+1)=-6.7(-x-3)

9 x - 2.5 (x + 1) = - 6.7 (- x - 3)

x = - 113

Solution steps

9 x - 2.5 (x + 1) = - 6.7 (- x - 3)

Multiply both sides by

10

90 x - 25 (x + 1) = - 67 (- x - 3)

Expand

- 25 (x + 1) : - 25 x - 25

90 x - 25 x - 25 = - 67 (- x - 3)

Add similar elements:

90 x - 25 x = 65 x

65 x - 25 = - 67 (- x - 3)

Expand

- 67 (- x - 3) : 67 x + 201

65 x - 25 = 67 x + 201

Move

25

to the right side

65 x = 67 x + 226

Move

67 x

to the left side

- 2 x = 226

Divide both sides by

- 2

x = - 113

\frac{2 z - 4}{5} = \frac{3 z + 3}{10}

- 110 = 7 (8 b + 2) + 6 b

0.2 b = 10

\frac{f}{3} = 9

\frac{5}{4} b = 2
