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):
=?

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?)

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):

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.
