Question

what letters do you need to get rid of first to solve the equation
`(x)/(z )`
`- c for x`

Answer 1

You have the following equation:

`y=(x)/(z)-c`

In order to determine which of the previous letter you need to get rid off, to solve for x, you consider it is necessary to eliminate additional terms in the side of the equation where the variable is.

In this case, such additional term is - c.

Hence, the letter you need to get rid off is letter c.
