Problema Solution
solve following system of equations by graphing
x-y=1
x+y=7
Answer provided by our tutors
we need to draw the graphs of the functions x-y=1 and x+y=7
click here to see the graph
by finding the intersection point we find the solution of the system of equations
x = 4 and y = 3
Indeed
4 - 3 = 1
4 + 3 = 7
the solution of the system of equations is x=4 and y=3.
