A single element in a mathematical equation is known as a variable. In algebra, a variable is usually a letter, like "X" or "Y," that is solved for.
In solving an inequality you generally use the same methods as for solving an equation. The main difference is that when you multiply or divide each side by a negative, you have to switch the direction of the inequality sign. The solution to an equation is often a single value, but the solution to an inequality is usually an infinite set of numbers, such as x>3.
A term is a single part of an expression or of an equation in algebra.
False
An equation is a statement that two (preferably different) expressions are EQUAL to each other (hence EQUAtion) An expression is series of numbers, variables, and operations which makes mathematical sense. (when I say "makes mathematical sense" I simply mean that "5x + -/* -2" would not count as an expression since you have a subtraction sign divided by a multiplication sign) Since an equals sign is not a number, variable, NOR an operation, you canNOT have an equals sign in a single expression (that would turn it into an equation). For example... Equation: 3x + 2 = 9/x - 7 Expression: 3x + 2 or Expression: 9/x - 7 Note how the equation serves to join two different expressions together. An expression alone cannot provide any useful information (in general). Rather, an equation is needed in order to draw useful mathematical conclusions.

None. -42 is a single integer, not an equation nor an inequality. So there are no solutions.
An example of an element with a symbol for a single atom is hydrogen, which is represented by the symbol "H".
There is no single inequality for this equation. Inequalities could include y-3x-5 > 0 y-3x-5 < 0 y-3x-5 != 0
A numerical expression is ' 2 + 3' A numerical equation is ' 2 + 3 = 5'.
The general equation for a single displacement reaction is: A + BC → AC + B. This type of reaction occurs when one element displaces another in a compound, resulting in the formation of a new compound and a free element.
A term in algebra is a single part of an expression or of an equation separated by mathematical signs.
