x = \frac{2}{3}

Decimal Notation

x = 0.66666 \dots

Solution steps

x + 2 (x + 1) = 4

Expand

2 (x + 1) : 2 x + 2

x + 2 x + 2 = 4

Add similar elements:

x + 2 x = 3 x

3 x + 2 = 4

Move

2

to the right side

3 x = 2

Divide both sides by

3

x = \frac{2}{3}

x, x + 4 y = 5

\frac{3}{5} = \frac{6}{10}

- 8 (1 + 4 p) + 7 p = - 25 - 8 p

x, 8 x - 6 y = 1

x, \frac{x}{2} + \frac{y}{4} = 1
