It helps to visualize the problem and to think better about the way(s) you're going to solve it. After you draw a picture, you place there the known information, and denote by a letter the unknown(s). Since you've organized everything on the picture, it's easier to relate things with each other by using the knowledge of geometry. For example, if the equation contains more than one variable, you can express the variable for which you want to solve the equation in terms of other variable(s) (the geometric formulas are very handy).

You can have more than one variable, but it would take longer to solve.
You may want to be a little more specific about what your question is asking....... you can solve a variable in an equation or expression. For example: 1+2=y just remember, you arnt necessarily "solving" a variable, but I guess you could say that considering a variable can change continuously. Be sure to consider that if you do "solve" a variable you end up with a constant ( a never-changing number) therefore, it is no longer a variable, but just an answer. Hope that helped! :-)

The answer depends on which properties you have in mind. And since you have not bothered to share that crucial bit of information, I cannot provide a more useful answer.
false
A system of equations can have any number of inequalities.
Some can but some dont... p.s no offense your dumb xD
Compound inequalities are inequalities that have more than one sign, for example, 5
(x+y) is the same as x+y 3(x+y) is 3 times as much. You multiply both x and y with 3 = 3x+3y 3(2x+4y) is the same as 3*2x+3*4y = 6x+12y This is the general start of how to "solve" and do calculations with parentheses. I am sure other people can add more examples with higher difficulty Regards.
Assuming you meant to insert an = between xyy and 4, then xyy=4. Divide by x to get yy=4/x. yy is y^2, so y^2=4/x. Take the square root of both sides to get y=±√(4/x)
