$color(blue)(x =15$

$4-2(x-7)=-12$

$4-2*x + (-2) *(-7)=-12$

$4-2x + 14=-12$

$-2x + 14+4=-12$

$-2x + 18=-12$

$-2x =-12-18$

$-2x =-30$

$x =(-30)/(-2)$

$color(blue)(x =15$

$x=15$

We can distribute the $-2$ on the left side to get

$4-2x+14=-12$

Next, we can simplify the left side constants to get

$-2x+18=-12$

Next, subtract $18$ from both sides to get

$-2x=-30$

Lastly, we can divide both sides by $-2$ to get

$x=15$

Hope this helps!
