9x-4.9(2x+5)=x-(9x-7.9)

9 x - 4.9 (2 x + 5) = x - (9 x - 7.9)

x = 4.5

Solution steps

9 x - 4.9 (2 x + 5) = x - (9 x - 7.9)

Expand

- 4.9 (2 x + 5) : - 9.8 x - 24.5

9 x - 9.8 x - 24.5 = x - (9 x - 7.9)

Add similar elements:

9 x - 9.8 x = - 0.8 x

- 0.8 x - 24.5 = x - (9 x - 7.9)

Expand

x - (9 x - 7.9) : - 8 x + 7.9

- 0.8 x - 24.5 = - 8 x + 7.9

Move

24.5

to the right side

- 0.8 x = - 8 x + 32.4

Move

8 x

to the left side

7.2 x = 32.4

Divide both sides by

7.2

x = 4.5

\frac{5 + m}{6} = 4 m

5 x - 6 = 3 x + 18

\frac{2}{3} - \frac{1}{9} = 35

- 4 x + 3 (2 x - 5) = 31

3 - \frac{1}{5} x = - 7
