The correct answer is 516 - 8.516 - 8 is an inconsistent number pair.If there is nothing common between the two equations then it can be called inconsistent.A consistent system of equations has at least one solution, and an inconsistent system has no solution.A system of linear equations is a group of two or more linear equations having the same variables. If there is nothing common between the two equations then it can be called inconsistent.Example for Inconsistent equation:Inconsistent equations are defined as two or more equations that are impossible to solve based on using one set of values for the variables.An example of a set of inconsistent equations is x+2=4 and x+2=6.Example for Consistent equation:Let's take an example of consistent equations as x + y = 6 and x “ y = 2 there is one solution in common.Similarly, in the equations x + y = 12 and 3y = x, there is also one solution in common hence we can call them consistent equations.
