3x+2(x-1)=9x+4

3 x + 2 (x - 1) = 9 x + 4

x = - \frac{3}{2}

Decimal Notation

x = - 1.5

Solution steps

3 x + 2 (x - 1) = 9 x + 4

Expand

2 (x - 1) : 2 x - 2

3 x + 2 x - 2 = 9 x + 4

Add similar elements:

3 x + 2 x = 5 x

5 x - 2 = 9 x + 4

Move

2

to the right side

5 x = 9 x + 6

Move

9 x

to the left side

- 4 x = 6

Divide both sides by

- 4

x = - \frac{3}{2}

\frac{2}{3} (9 w - 24) = - 10

2 (x - 9) + 4 = 30

- 10 = \frac{w}{3}

10.6 = 2.9 b + 1.9

\frac{2 x - 1}{5} = \frac{3 x + 1}{10}
