I know how to add unlike fractions , but i don't know how to add them if they contain an X... like this.
1/x + 2/3 = 3/x
I'm supposed to solve for x. Can you please explain how to do this. :-)

You should be able to get this just by looking at it, but the method would be to multiply to get a demoninator of 3x - i.e.
3/3x +2x/3x =9/3x
(2x+3)/3x=9/3x
2X+3 = 9
take it from there.

Probably something in the water that conservatives drink. We have calculators and spell checkers on our computers. You are complaining about skills that are not really needed. But the kids you complain about can balance a chemical reaction, explain Newton's three laws of motion with examples, explain the destructive social history of racism and Jim Crow laws, derive the quadratic equation, write a Java program to add fractions, write the equation for an ellipse, use calculus to derive the area under a formula, provide an explanation of the role of the 13th amendment to complete the transition of the USA from a mercantile economy to a capitalist one and then explain the necessity of socialism to modify capitalism to prevent the abuses of the middle class and allow it to grow, ensuring a stronger democratic representative government.

1) Find the LCM
2) Subtract 2/3 -1/x
I think that is how you do it but I am not that sure.
