You cannot go beyond x = k unless you know the value of k. And in that case, the equation is solved so there is nothing further to do!
Without an equality sign the given expression can't be considered to be an equation.
You solve the equation the same way as you would any other equation. Whether the variable is a fraction or otherwise will only become clear once you solve the equation. In other words, you don't initially KNOW whether the solution will be a fraction or not.
I'm going to solve [ 2b = 10 ] for you, but I'm not going to do it in the best way.The best way is for you to make a date with your teacher to sit down and reviewsome of this stuff, so that you know how to do it.The way I'm going to do it, you'll have the solution to [ 2b = 10 ], but there will bethree problems with it:-- Nobody needs that information.-- You won't learn anything.-- If you need to solve [ 3d = 15 ] tomorrow, you'll be just as clueless as you are today.Here's the solution, and the method of finding it:1). Write down the equation :2b = 102). Divide each side of the equation by 2 :b = 5
You could multiply the first equation by 3 and the second by -5 and eliminate the x... OR you could multiply the first equation by 7 and the second by 10 and eliminate the y. Either way works.
