y= x+4: x= y-4

Step-by-step explanation

you have to do the inverse of whatever you figuring out so to solve for Y you would add x to both sides and once you have Y alone that's your answer and for X you subtract Y and divided both sides by -1 because lone variable can never me negative.

−cz+6z=tz+83 solve for z

nasty-shy [4]

To answer this item, we combine all terms involving the variable z to only one side of the equation. All else will be placed on the other side of the equation. This is as follows,

-cz + 6z = tz + 83

Transposing,
-cz - tz + 6z = 83

Factoring z out,
z(-c - t + 6) = 83

Dividing the equation such that z will be left on one side of the equation,

<em> z = 83 / (-c - t + 6)</em>
