Question

2x + 2y = –6
3x – 2y = 11

What is the solution to the system?
(–1, –7)

(1, –4)

(2, –1)

(3, –2)

Answer 1

graph the two lines and you will get your answer

Answer 2

if you add you two equations together what would you get?

Answer 3

still not understanding

Answer 4

you can eliminate y and solve for x

Answer 5

does that make sense you would get 5x = 5, solve this for x and plug back into one of the equations to solve for y

Answer 6

does this help?

Answer 7

i guess

Answer 8

because 2x+3x = 5x right?

Answer 9

and 2y + -2y = 0

Answer 10

It is 1, -4. You can just plug in all the answers and see which one would give you the right answer within the equation.

Answer 11

and -6 + 11 = 5

Answer 12

okay

Answer 13

that works too. Sometime though you wont be given the solutions so they way I was tring to show you would help you in any problem. :)

Answer 14

when you see that 5x = 5 , then x = 1,

Answer 15

then when you plug 1 in for x into either equation you get y= 4

Answer 16

Hope that helped
