Anything better? by levik)
Hello everyone. I am new to Flooble, so go easy on me for this one.
equation 1: (x4)(y^2+3)=0 (assuming x and y are real)
there are two variables, but we know that x=4 is one of them. This equation is the same concept as the original solution. There is a product that equals zero, but one of them (y^2+3) can not equal therefore it has to be the other, thus x=4.
Others that fit the same pattern are (x+3)e^y=0 and we know x must be 3
equation 2: (x5)(y5)=0
This one is questionable...see what you think. It does answer the question "...and still find the value of one?" We know that "one" of the variables must = 5, we just don't know which one it is.
