Rewrite the expression x y z = 3 ⋅ a x y z = 3 ⋅ a xy z = 3a x y z = 3 a Move all terms not containing y y to the right side of the equation Tap for more steps Subtract x x from both sides of the equation y z = 3 a − x y z = 3 a x Subtract z z from both sides of the equation y = 3 a − x − z y = 3 a x zExplanation Given, y/ (x z) = (y x)/z = x/y y z = x y x 2 y z x z ( 1) Also x y = y x z ⇒ x 2 x z = y 2 ( 2) Using (1) and (2), we get yz = xy yz y 2 2yz = xy y 2 2z = x y3(xy) (yz( z x)= 12x³
