-2(z+4)=-37

We move all terms to the left:

-2(z+4)-(-37)=0

We add all the numbers together, and all the variables

-2(z+4)+37=0

We multiply parentheses

-2z-8+37=0

We add all the numbers together, and all the variables

-2z+29=0

We move all terms containing z to the left, all other terms to the right

-2z=-29

z=-29/-2

z=14+1/2
