3x-y=-6
x+y=2
Please, I really need help. OMGGGZZZZ I NEED HELP NOW PPLLZZZ!!!!!!!
(hehehe...I know i shouldn't say that...)
$\displaystyle 3x - y = -6, (1)$
$\displaystyle x + y = 2, (2)$
$\displaystyle (1) + (2): 4x = -4 \implies x = -1$.
Substitute back into $\displaystyle (2)$
$\displaystyle -1 + y = 2$
$\displaystyle y = 3$.
Therefore, your solution is $\displaystyle (x, y) = (-1, 3)$.
