Question 443015: solve the systems of equations by graphing x + y=14 and x - y=2

You can put this solution on YOUR website!
x + y = 14
y = 14 - x


x - y = 2
-y = 2 - x
y = x - 2


Graph the equations and find that they have an intersection at (8, 6)


Therefore, x = 8 and y = 6.


Check:


8 + 6 = 14
14 = 14


8 - 6 = 2
2 = 2
