x-9-2(x+3)=-12

x - 9 - 2 (x + 3) = - 12

x = - 3

Solution steps

x - 9 - 2 (x + 3) = - 12

Move

9

to the right side

x - 2 (x + 3) = - 3

Expand

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

x - 2 x - 6 = - 3

Add similar elements:

x - 2 x = - x

- x - 6 = - 3

Move

6

to the right side

- x = 3

Divide both sides by

- 1

x = - 3

x^{1} = - 2

\frac{2 x - 1}{3} = \frac{4 - x}{6}

z, - p (51 + z) = d z + 84

\frac{8}{3} x + \frac{1}{6} = \frac{2}{3}

\frac{4 x}{3} = 8
