Respuesta :
In this example the equation has no solution. This is because, in algebra, the variables are what is solved for. Here, through the combination method, Heather has determined that 0 = 60, which is not true. Zero cannot equal a number other than itself; additionally there are no variables that were solved for in this equation. By this it is meant that "x" is not given a value and "y" is not given a value. These two values would be used for coordinates to plot the line on a graph
The correct answer is:
The equation has no solution; therefore, the system of equations has no solution.
Explanation:
When solving a system of equations, after we combine the equations, if we find that there is no solution, that means that there is no solution to the entire system of equations.
