With a formula, you know the variable's value, and you have to calculate the value of the function of it.
With an equation, you know the function's value, and you have to calculate the value of the variable.
Answer 1 == In an open sentence (an equation or inequality with a variable in it), when a number replacing the variable makes the sentence true, then it is a solution.
You replace the variable by the number, do all specified calculations, and then check whether the resulting inequality is true or false. This is basically not very different from checking a solution of an equation.
To substitute an inequality in an equation, first identify the variable in the equation that you want to replace. Then, use the inequality to express that variable in terms of others, ensuring the substitution maintains the relationship dictated by the inequality. It’s important to remember that inequalities can change the nature of the solution set; for instance, if you substitute a variable with an inequality, the resulting equation may have a range of solutions rather than a single value. Finally, solve the equation as usual but consider the implications of the inequality in your final results.
This are variable introduce into equation as well as to inequality where a surplus variable is introduced.
To solve a linear equation or inequality, first isolate the variable on one side of the equation or inequality. For an equation, use operations like addition, subtraction, multiplication, or division to simplify until the variable is alone (e.g., (ax + b = c) becomes (x = (c-b)/a)). For an inequality, follow similar steps but remember to reverse the inequality sign if you multiply or divide by a negative number. Finally, express the solution in interval notation or as a graph on a number line, depending on the context.

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.
No, you can only simplify an expression. To solve for a variable, it must be in an equation.
An equation has an equal sign, which means that we know what the variable is equal to :)

Solve the inequality and enter your solution as an inequality comparing the variable to the solution. -33+x<-33
They make up the solution set.

An equation or an inequality that contains at least one variable is called an open sentence. ... When you substitute a number for the variable in an open sentence, the resulting statement is either true or false. If the statement is true, the number is a solution to the equation or inequality.
