Q. If 3xy=7 3 x y=7 , which of the following expressions is equivalent to x x ?\newlineChoose 11 answer:\newline(A) 73y \frac{7}{3 y} \newline(B) 3y7 \frac{3 y}{7} \newline(C) 7y3 \frac{7 y}{3} \newline(D) 21y 21 y
  1. Given Equation: We are given the equation 3xy=73xy = 7 and we need to solve for xx in terms of yy.\newlineTo isolate xx, we divide both sides of the equation by 3y3y.\newlinex=73yx = \frac{7}{3y}
