OpenStudy (gigi1103):

oh i love these kind of problems

OpenStudy (gigi1103):

one sec

OpenStudy (gigi1103):

its d wanna know why?

OpenStudy (anonymous):

SURE

OpenStudy (gigi1103):

why there is a x2 you multiply it so 2 x -4 =8

OpenStudy (gigi1103):

then -4 - 0=-4

OpenStudy (gigi1103):

its really simply

OpenStudy (anonymous):

ok thx can u hlp with more plz

OpenStudy (gigi1103):

sure but i warn you i have my own math lol

Which ordered pair is the solution to the system of equations? A. (2, −1) B. (1, −9) C. (−2, −2) D. (−6, −3)

OpenStudy (gigi1103):

wheres the thing

OpenStudy (anonymous):

OpenStudy (gigi1103):

ok you try and ill tell you if your right

OpenStudy (anonymous):

can you tell me how to do it

OpenStudy (anonymous):

im not sure where to start

OpenStudy (♪chibiterasu):

You can just plug in the values into the equation. (x, y) plug in the numbers for x and y

OpenStudy (gigi1103):

ok just fill in 2 - 4 * -1

OpenStudy (gigi1103):

=?

OpenStudy (♪chibiterasu):

If the ending result matches, it is the solution

OpenStudy (gigi1103):

ok so you try it

OpenStudy (anonymous):

ohhh ok

OpenStudy (anonymous):

is it A

OpenStudy (♪chibiterasu):

So try it for both of them. 2 - (4 * -1) = 6 (does it equal 6?) (3 * 2) + (-1) = -8 (does it equal -8?)

OpenStudy (gigi1103):

good job !!

OpenStudy (♪chibiterasu):

hmm

OpenStudy (♪chibiterasu):

3*2 = 6 6 + (-1) = 5

OpenStudy (gigi1103):

still need my help? and are you sure

OpenStudy (gigi1103):

so not a try again

OpenStudy (anonymous):

no I think im good now

OpenStudy (gigi1103):

ok ;D

OpenStudy (anonymous):

thx

OpenStudy (♪chibiterasu):

But hold on, it's not A. Let's try the other ones. Let's try (-2, -2) -2 - (-4 * -2) = 6 (3 * -2) - 2 = -8

OpenStudy (♪chibiterasu):

Woops. That should be a positive 4.
