  • Wish i could but it looks complicated
  • Combine like terms: 4XY + 2 = X + 8Y. Let's start by isolating Y. Move all terms with "Y" to the left side, and all other terms to the right side: 4XY + 2 ( - 2 - 8Y ) = X + 8Y ( - 2 - 8Y ). Simplify. 4 XY - 8Y = X - 2. Factor out Y. Y ( 4X - 8 ) = X - 2 Complete isolation of Y. Y = X - 2 / ( 4X - 8 ). Factor out X-2. Y = X - 2 / ( 4 ( X - 2 ) ) Simplify Y = 1/4. Now substitute Y = 1/4 into the original equation 4X(1/4) + 2 = X + 8(1/4) Simplify X + 2 = X + 2. This is true for all X. So, Y = 1/4 and X could be anything. Actually, in general, you can never solve one equation independently for two variables, so, this should be no surprise.
  • Yes, I can. So can many other people. But if I were you I'd google a good homework help site. Of course you've probably either solved it or failed because this is an old question.
