"Solve an equation" means "find out, for which values of the variable or variables is the equation true".

It means that you prove that an equation is true for ALL values of the variable or variables involved.

If all the values of the "independent" variable (x) are different then it is a function.If there are any repeats of the independent variable, the corresponding dependent variable, y, must be the same.If all the values of the "independent" variable (x) are different then it is a function.If there are any repeats of the independent variable, the corresponding dependent variable, y, must be the same.If all the values of the "independent" variable (x) are different then it is a function.If there are any repeats of the independent variable, the corresponding dependent variable, y, must be the same.If all the values of the "independent" variable (x) are different then it is a function.If there are any repeats of the independent variable, the corresponding dependent variable, y, must be the same.

an equation that's true for all values is an identity.

The solution to a system on linear equations in nunknown variables are ordered n-tuples such that their values satisfy each of the equations in the system. There need not be a solution or there can be more than one solutions.

Find values for the variable that satisfy the equation, that is if you replace those values for the variable into the original equation, the equation becomes a true statement.

The graph of an equation is a visual representation of the values that satisfy the equation.

When an equation has a variable in it (only one), then there are only certainvalues the variable can have that will make the equation a true statement."Solving" the equation means finding those values for the variable.

In mathematics, the term "root" refers to the solution(s) of an equation. Specifically, the roots of an equation are the values that make the equation true when substituted for the variable. The number of roots depends on the degree of the equation.

They are called the "solutions" of the equation.

The goal is to find what value or values the variable may have, to make the equation true.

The solution to an equation consists of the value (or values) of all the variables such that the equation is true when the variable(s) take those values.

It is finding the values of the variable that make the quadratic equation true.

It's a single linear equation in two variables. The graph of the equation is a straight line; every point on the line is a set of values that satisfy the equation. In other words, there are an infinite number of pairs of (x,y) values that satisfy it. In order to figure out numerical values for 'x' and 'y', you would need another equation.
