Question

Identify the solution(s) of the system of equations, if any.
9x + 2y = 2
8x - 2y = 4

Answer 1

no need here to multiply any equations here just add both equations together
that equals
9x+8x = 2+4
x= 6/17

Answer 2

ok...I see

Answer 3

y=-10/17

Answer 4

(6/17, -10/17)

Answer 5

So...so let's go back a second and lets talk about how you got to the -10/17 answer.

Answer 6

ok...I think I see....you did the -4/1(6/17) to equal the -10/17, right?

Answer 7

u know how to get the x value by elimination method okay ?

Answer 8

yes

Answer 9

good then u have the value of x substitute the value of x in any of the two equations u have and u would find the answer of y

Answer 10

like in this example

Answer 11

x= 6/17
9x + 2y = 2
soo 9*(6/17)+2y=2

Answer 12

Oh yeah...duh. I think my mind is slowly shriveling up. LOL

Answer 13

ha ha I was just typing the same thing to reiterate the answer.

Answer 14

Thanks so much!!

Answer 15

it is okay when u have the two values substitute both of them in one of the equations to confirm ur answer ^_^ good luck

Answer 16
