Hello!
let's make the following solution:
[tex] -18*(2h+4)+12 = -74 [/tex]
[tex]-18*2h - 18*4 = - 74 - 12[/tex]
[tex]-36h - 72 = - 86[/tex]
[tex]-36h = -86+72[/tex]
[tex]-36h = -14\:\:simplify\:by\:(-1)[/tex]
[tex]36h = 14[/tex]
[tex]h = \dfrac{14}{36}[/tex]
[tex]h = \dfrac{14}{36}\frac{\div2}{\div2}[/tex]
[tex]\boxed{\boxed{h = \dfrac{7}{18}}}\end{array}}\qquad\checkmark[/tex]
