10x+2x+3(x-8)-30=0

10 x + 2 x + 3 (x - 8) - 30 = 0

x = \frac{18}{5}

Decimal Notation

x = 3.6

Solution steps

10 x + 2 x + 3 (x - 8) - 30 = 0

Add similar elements:

10 x + 2 x = 12 x

12 x + 3 (x - 8) - 30 = 0

Move

30

to the right side

12 x + 3 (x - 8) = 30

Expand

3 (x - 8) : 3 x - 24

12 x + 3 x - 24 = 30

Add similar elements:

12 x + 3 x = 15 x

15 x - 24 = 30

Move

24

to the right side

15 x = 54

Divide both sides by

15

x = \frac{18}{5}

5 + 14 x = 9 x - 5

\frac{3 a - 1}{8} = \frac{a + 9}{4}

- 8 - 3 (w + 13) = 4 (w + 11) - 7 w

3 (n + 11) - 5 n = - 2 (n - 12) + 9

- 8 (3 x - \frac{1}{4}) = 2 (9 - 7 x)
