Question

Solve the system of equations by graphing. Then classify the system.
x+y=11
x-y=-7

Answer 1

The solution for this question is non. so I need help?

Answer 2

well easiest way is making everythign in terms of y. (or x wtv is easier)
so you get
y=-x+11 and y=x+7 then you just plug in two points for each to graph it because that is all you need when the lines are linear.

Answer 3

then you compare the two so you get x+7=-x+11
so your x=2 and then plug into y and you get 9
get it :)?

Answer 4

okay, may you explain more.

Answer 5

sure what dont u get?

Answer 6

Everything becoz I try to solve it but there is any solution? hle plz

Answer 7
