Answer:
7
Step-by-step explanation:
To solve this, we have to solve for h.
We can use order of operations to figure this one out.
[tex]18h-9h-7h+3=17\\18h-9h-7h=14[/tex]
Now that every variable on the left side of the equation has an h, we can factor.
[tex]h(18-9-7)=14\\h=\frac{14}{18-9-7} \\h=\frac{14}{2} \\h=7[/tex]
