A number is an expression. It is not an equation, or an inequality, since it doesn't have an equal sign, or an inequality (greater than, less than, etc.) sign.
An algebraic equation or inequality can have a solution, an algebraic expression cannot. If substituting a number in place of a variable results in the equation or inequality being a true statement, then that number is a solution of the equation or inequality.
-15 + x100 is an expression, not an equation nor inequality. There is, therefore, no solution.-15 + x100 is an expression, not an equation nor inequality. There is, therefore, no solution.-15 + x100 is an expression, not an equation nor inequality. There is, therefore, no solution.-15 + x100 is an expression, not an equation nor inequality. There is, therefore, no solution.
An expression due to the lack of the equal sign.
simply put, an expression has no "equal to" sign (=). and equation has the "equal" to sign and and inequality has either one of these signs <, >
There is no equation or inequality, just an expression. An expression cannot have an answer.
No, an expression cannot have any solutions. It is an expression, not an equation (or inequality).
term
x5 is an expression, not an equation nor an inequality. An expression cannot be solved.
No, you can only simplify an expression. To solve for a variable, it must be in an equation.
b2.1 is an expression, not an inequality.
