part a)![x=3, y=-2](/tex.php?f=x=3, y=-2)
part b) verification in the procedure
part c) the graph in the attached figure
step-by-step explanation:
we have
part a) use substitution to find the solution to the systems of equations
in the equation a isolate the variable x
substitute equation c in equation b
find the value of x
the solution is equal to
part b) algebraically verify your answer to part a
we have that
the solution is![x=3, y=-2](/tex.php?f=x=3, y=-2)
verify in the equation a and in the equation b
equation a
substitute the value of x and the value of y in the equation and then compare
)=5[/tex]
equation b
substitute the value of x and the value of y in the equation and then compare
therefore
the point
satisfy both equations
hence
the point
is the solution of the system of equations
part c) graphically verify your answer to part a
we know that
the intersection point both graphs is the solution of the system of equations
using a graphing tool
see the attached figure
the intersection point is equal to![(3,-2)](/tex.php?f=(3,-2))
therefore
the point
is the solution of the system of equations
