3-x-2(x-3)=3

3 - x - 2 (x - 3) = 3

x = 2

Solution steps

3 - x - 2 (x - 3) = 3

Subtract

3

from both sides

3 - x - 2 (x - 3) - 3 = 3 - 3

Simplify

- x - 2 (x - 3) = 0

Expand

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

- x - 2 x + 6 = 0

Add similar elements:

- x - 2 x = - 3 x

- 3 x + 6 = 0

Move

6

to the right side

- 3 x = - 6

Divide both sides by

- 3

x = 2

(a + x)^{2} - a (a - 1) = x^{2} + a^{2}

3 (2 x - 20) = - 15 (4 - 2 x) - 10 x

\frac{2}{3} = \frac{x}{100}

8 x + 16 = 0

3 x = 5 + 2 x
