Question 304837: please help me solve for what values of X and Y is
Answer by checkley77(12844) (Show Source): You can put this solution on YOUR website!
sqrt(9x^2-4y^2)= 3x-2y SQUARE BOTH SIDES.
9X^2-4Y^2=9X^2-12XY+4Y^2 SUBTRACT 9X^2 FROM BOTH SIDES.
-4Y^2-4Y^2=12XY
-8Y^2=12XY
12X=-8Y^2/Y CANCEL THE Y TERM.
12X=-8Y
X=-8Y/12
X=-2Y/3 ANS. FOR X.
-8Y=12X
Y=12X/-8
Y=-3X/2 ANS. FOR Y.
