A system of two equations with two unknowns is given:

Notice that the variable y is isolated in the second equation. Then. we can solve the system using the substitution method by replacing y in the first equation by the expression from the second equation:

This way, we have obtained a single equation with one unknown that we can solve as usual. Solve for x:

Replace x=-1 into the equation for y to find its value:

Then, the solution to the system is x=-1 and y=-2. As an ordered pair (x,y), the solution point for the given system is:
