65-5*z =30

To solve the equation 65-5z = 30, we want to isolate the variable z on one side of the equation.

Let's start by moving the constant term to the right side of the equation.

Subtracting 65 from both sides, we get:

65 - 5z - 65 = 30 - 65

Simplifying:

-5z = -35

Now, we can isolate z by dividing both sides of the equation by -5:

-5z / -5 = -35 / -5

Simplifying:

z = 7

So the solution to the equation is z = 7.
