- (x - 3) - 4(x - 1) = 14

Let's go through this....

- (x - 3) - 4(x - 1) = 14       simplify on the left

-x + 3 - 4x + 4 = 14

-5x + 7  = 14        subtract 7 from both sides

-5x  = 7               divide both sides by -5

x = -7/5

$${\mathtt{\,-\,}}\left({\mathtt{x}}{\mathtt{\,-\,}}{\mathtt{3}}\right){\mathtt{\,-\,}}{\mathtt{4}}{\mathtt{\,\times\,}}\left({\mathtt{x}}{\mathtt{\,-\,}}{\mathtt{1}}\right) = {\mathtt{14}} \Rightarrow {\mathtt{x}} = {\mathtt{\,-\,}}{\frac{{\mathtt{7}}}{{\mathtt{5}}}} \Rightarrow {\mathtt{x}} = -{\mathtt{1.4}}$$
