isolate the variable
No, you can only simplify an expression. To solve for a variable, it must be in an equation.
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.
each of the four regions created on the coordinate plane by the x- and y-axes.
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.
If the equal sign in a linear equation in two variables is replaced with an inequality symbol, the result is a linear inequality in two variables. 3x-2y>7 x<-5
This are variable introduce into equation as well as to inequality where a surplus variable is introduced.
Slack variable is a variable that is added to a constraint to switch form an inequality to equatlity equation.

You normally "solve" something when there is a variable involved. In this case there is no variable. All you have to do is decide whether it is true or false. If this is derived from an original equation (or, in this case, inequality) which involved variables, then if the equation (or inequality) without variables is true, it means it is true for ANY value of the variable. If it is false, the original equation (or inequality) can't be satisfied by any value of the variable.
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.

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.

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.

An expression cannot be solved; an equation or an inequality may be.
