take all the terms on one side and subtract, the equations
OpenStudy (zzr0ck3r):
the first thing I did was -2(x+3y=2)
OpenStudy (ganpat):
multiply equation 1 by 2.. So, 2x + 6y = 4 ----- eqtn 1 2x - 3y = 22 ---- equation 2 subracting... 9y = -18 so y = -3.. and x = -7..
OpenStudy (goformit100):
i was correct
OpenStudy (ganpat):
sorry, x =11..
