What is the solution to the equation \(1 - \frac{z}{5} = 9\)?

A. \(z = 50\)
B. \(z = 44\)
C. \(z = -2\)
D. \(z = -40\)

Asked by mjchey

Answer (2)

1 − 5 z ​ = 9
add 5 z ​ to both sides.
1 = 9 + 5 z ​
subtract 9 to both sides.
− 8 = 5 z ​
multiply 5 to both sides.
− 40 = z
Your answer is D) z = -40

The solution to the equation 1 − 5 z ​ = 9 is z = − 40 . Therefore, the correct answer is option D. This is found by isolating z through algebraic manipulations.
