# How do you solve for x: 4x+12(-x-3) = 2x-4(-x)-3^2?

Aug 7, 2016

$x = - \frac{27}{14}$

#### Explanation:

Notice that a large part of solving this equation involves the correct order of operations as well. Maths is seldom little compartments, but one huge subject full of different concepts and methods, but they all intertwine.

$4 x + 12 \left(- x - 3\right) = 2 x - 4 \left(- x\right) - {3}^{2}$

$\cancel{4 x} - 12 x - 36 = 2 x + \cancel{4 x} - 9$

$- 36 + 9 = 2 x + 12 x$

$- 27 = 14 x$

$- \frac{27}{14} = x$
