Solve the problem using the + sign for the variable. Then solve the problem using the - sign for the variable. Report your answer as the answer that you got using + or the answer that you got using -.

Square both sides of the equation to get rid of the radical sign. Then just solve as you normally would. Good luck! :-)
That will obviously depend on the specific problem. If you have an equation with a variable under a square root sign, it often helps to square both sides of the equation.
Without an equality sign the given expression can't be considered to be an equation

meaning to evaluate the variable in an expression. An algebraic expression is also a problem that contains no equals sign and you don't solve it, rather you simplify it.It means to solve something.
When you have a negative variable in an equation that you are trying to solve for, you multiply each side of the equation by -1. If it is an inequality such as <, you would flip the sign to > and vice versa.
An equations is a math sentence that asserts the quality of two expressions. Basically it's a math sentence that contains a variable and and equal sign. Is it a problem? Only if you have to solve it! It's easily solved by doing the inverse operation stated with the variable. Ex: n - 32 = 16 To solve you ADD 32 to both sides of the = sign. (to each expression) a - 32 + 32 cancels out so you're left with just "n" = 16 + 32. Add and you get n = 48
X could be a sign for multiplication, or it could also be a variable. A variable is a letter representing a number.

It is not an equation because there is no equal sign

u can't solve it because there has to be one variable to solve and equal sign, ex. 4x=20. U can simifly though distrubute the n to 4 and -x. ur answer is 4n-nx
