insert y=3x-4 in for the y varible in -3y=-9x+12
no, not yet, cmon, do the equation here so i can check u.
i don't know how
y=3x-4, put that in the second equation where y is like this. -3+3x-4=-9x+12
now do the math
man, i can't do it all for you, go back and re read the lesson
i'm not here to give you answers, i'm here to help you help yourself
just walk me though the steps
ok, simplify this, -3+3x-4=-9x+12
combine -3 and -4 so 3x-7=-9x+12
ok thats -4,8
now isolate the x variables on one side.
OMG SCREW IT IM GOING WITH D
3x+9x=12x and 12+-9=3
so we have 12x=3
i already picked d
now just simplify
it doesnt matter
well, thanx for throwin away my time.
