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!
