A linear equation represents a line. A linear inequality represents part of the space on one side (or the other) of the line defined by the corresponding equation.
There are many simple questions in everyday life that can be modelled by linear equations and solved using linear programming.
Solving linear systems means to solve linear equations and inequalities. Then to graph it and describing it by statical statements.
Inequalities have greater than, less than, greater than or equal to, or less than or equal to signs. Equations have an equal sign.
Many problems in economics can be modelled by a system of linear equations: equalities r inequalities. Such systems are best solved using matrix algebra.
A system of linear inequalities
There are many simple questions in everyday life that can be modelled by linear equations and solved using linear programming.
They are not. An inequality cannot, by definition, be the same as an equation.
To solve it by coordinate graphs you would take a point from the line and plug in the X and Y value into the equations and or inequalities.
Somewhat, but the rules are a bit different for inequalities. Example. -2X > 4 X < - 2 See, sign changes when dividing by negative coefficient.
Linear equations or inequalities describe points x y that lie on a circle.
Equations have and can only have a = Inequalities have <, >, greater than or equal to, less than or equal to, or =
Solving linear systems means to solve linear equations and inequalities. Then to graph it and describing it by statical statements.
All linear equations are functions but not all functions are linear equations.
Inequalities have greater than, less than, greater than or equal to, or less than or equal to signs. Equations have an equal sign.
First degree equations ad inequalities in one variable are known as linear equations or linear inequalities. The one variable part means they have only one dimension. For example x=3 is the point 3 on the number line. If we write x>3 then it is all points on the number line greater than but not equal to 3.
The question contains two equations:5x - 6y = 15 5x + y = 2 There are no inequalities in the question.
It makes it allot less confusing. But, that is just my opinion.
