Solve the formula for the specified variable.

W=X+Xyz for z

z= (w-x)/ xy

Step-by-step explanation:

w= x+xyz solve for z

w= x+xyz, isolate the term that has z by subtracting x from both sides (because is the opposite of adding x to the term xyz we try to isolate)

w-x = xyz, divide both sides by xy assuming that xy≠0 (because is the opposite of multiplying z by xy to solve for z, and xy≠0  because we do not want to divide by 0)

(w-x)/xy = z

step-by-step explanation:

subtract 7, so the answer is x < = 3, or c.
