How do you rewrite the formula y=-3z/x to find z?

Answer 1

To solve y=-3z/x for z, you have to follow these steps:

1) multiply both sides by x

xy = -3z

2) divide both sides by -3

(xy)/-3 = z

Answer 2

y = -3z/x To manipulate this equation to solve for z, the first step is to get rid of the fraction by multiplying both sides by x

y(x) = -3z/x(x) When you simplify the right side, the x's cancel out.

xy = -3z Now the only thing keeping the z from being isolated is that -3. For this, divide both sides of the equation by -3

xy/-3 = -3z/-3 Now when you simplify, -3/-3 = 1. So the z is alone

xy/-3 = z
