How do you solve m=q/z-v solve for z

g100num [7]

Hello!

To solve whatever z is we have to get it by itself by using inverse operations. I will undo operations below.

m=q/z-v+v
m+v=q/z(z)
m+v+z=q
m+v+z-z=q-z
m+v=q-z
Here I will switch z to adding negative z so we can use the commutative property.
m+v= q+(-z)
m+v=-z +q
m+v-q=-z+q-q
m+v-q=z

We now have our formula for z. z=m+v-q. Hope this helps!

Step 1

Determine the straight-line depreciation rate

Divide the total cost by the number of years in the asset's useful life.

$\frac{\$35,000}{5}=\$7,000$
