Question

Solve the following system by using graph paper or graphing technology.

2x + 2y = -6
3x - 2y = 11

Answer 1

(-1, -7)
(1, -4)
(2, -1)
(3, -2)

Answer 2

so, graph them both, where they MEET, or TOUCH each other, that's the solution
at THAT POINT, "x" and "y" for the top and bottom equations are the exact same value

Answer 3

i dont need a graphing calculator

Answer 4

well, ok, then don't use one :)

Answer 5

ok im confused a little

Answer 6

well, on what part?

Answer 7

how to solve 2x+2y=-6

Answer 8

well, you're suggested to use a graph, either on paper or electronic

Answer 9

graph them both, where they MEET, or TOUCH each other, that's the solution
at THAT POINT, "x" and "y" for the top and bottom equations are the exact same value

Answer 10

i dont have electonic

Answer 11

well, lemme see on that, you're sitting at a computer
a computer is an electronic, in fact really just a large calculator
so :/

Answer 12

oh lol

Answer 13

well, I guess to graph them first, you'd need to solve for "y" each
so let's see what we get
y = (-6-2x)/2 ==> y = -x-3

(3x-11)/2 =y ==> y = 3x/2 - 11/2

Answer 14

so, those 2 equations

Answer 15

i cant find it
