Hannah tells you that when variables are in the denominator, the equation four over seven plus eight over x equals one over two becomes solvable. She explains, "There is a value for x that makes the denominator zero, and you can't divide by zero."

You can solve it by multiplying by the common denominator. Do you what it is?

Right, so if you multiply all the fractions by 10x they will cancel

ok i got 8x+30/ 10x =5x/10x

so -10?
anonymous
  • anonymous
how would -1o be the answer?

-10 is the solution to the equation.

I know. But doesn't that mean George is right?

  • anonymous
no, it means he's wrong. There is a value for x that makes the denominator 0, but the equation is still solvable. -10 is the solution for x. 0 is the value where it wouldn't have a solution. Like if you were trying to graph 3/x, you would be able to for all values except 0
