Step-by-step explanation:
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
