Question

Solve the formula for the indicate variable A=zv+x, for v

Answer 1

#1) subtract x from both sides

`a \: \: \: \: = \: \: \: \: \: \: \: \:zv + x \\ - x \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: - x`
you end up with

`a - x = zv`
#2) divide by z

`(a - x)/(z) = (vz)/(z)`
you end up with

`(a - x)/(z) = v`
