x = \frac{2}{7}

Decimal Notation

x = 0.28571 \dots

Solution steps

x + 2 (3 x - 1) = 0

Expand

2 (3 x - 1) : 6 x - 2

x + 6 x - 2 = 0

Add similar elements:

x + 6 x = 7 x

7 x - 2 = 0

to the right side

7 x = 2

Divide both sides by

7

x = \frac{2}{7}

2 lo g_{10} (7) = 3 x + lo g_{10} (49)

4 (x + 5) = 2 x + 34

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

6 + 2 x - 1 = \frac{x}{3}

7 p - (3 p + 4) = - 2 (2 p - 1) + 10
