- 9 + (4 + x) = (- 9 + 4) + x

Remove parentheses:

(a) = a

- 9 + 4 + x = (- 9 + 4) + x

Add/Subtract the numbers:

- 9 + 4 = - 5

x - 5 = (- 9 + 4) + x

Remove parentheses:

(- a) = - a

x - 5 = - 9 + 4 + x

x = x

Move

x

to the left side

0 = 0

Both sides are equal

True for all x

- 3.1 x + 7 - 7.4 x = 1.5 x - 6 (x - \frac{3}{2})

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

\frac{1}{2} x + 3 = 0

y + 9 y = 0

f, f (x + y) = f (x) + f (y)
