3x-y+-11)

Answer 1

Hoot! You just asked your first question! Hang tight while I find people to answer it for you. You can thank people who give you good answers by clicking the 'Good Answer' button on the right!

Answer 2

i am assuming the second equation is 3x-y=11 and not 3x-y+-11 ?

Answer 3

3x-y=-11

Answer 4

okay. do you know how to solve a system of equations?

Answer 5

not really im a blonde at math !

Answer 6

(x=-3,y=2)

plug them in and see if they match :)

Answer 7

2x+y = -4 ----------------------------- equation 1
3x-y = -11 ---------------------------- equation 2

add the two equations
2x+y + (3x -y) = -4 + (-11)
5x = -15
x = -3
substitute in equation 1
2(-3) + y = -4
-6+y = -4
y = 2
so x = -3, y = 2
or the ordered pair (-3,2) is the solution for the system of equations.
