The solution to the given system is (-30, 80).
What is a system of equations?
A system of equations is two or more equations that can be solved to get a unique solution. the power of the equation must be in one degree.
Line of best fit.
The solution to the given system of the equation of line is the point where both the lines intersect.
The method of substitution in which we express one variable in other variable's form and then you can substitute this value in other equation to get linear equation in one variable.
If there comes a = a situation for any a, then there are infinite solutions.
If there comes wrong equality, for example, 3=2, then there are no solutions, else there is one unique solution to the given system of equations.
From the given image attached below, we can see that the lines intersect at a coordinate point (x, y).
So, the location of these coordinate point on the xy-plane is (-30, 80).
Hence, the solution to the given system is (-30, 80)
