well,first add 6y to both sides :)
OpenStudy (anonymous):
y+2 = 3
y=1
OpenStudy (anonymous):
add it to the 2 and 3 or to the 5y and 6y?
OpenStudy (anonymous):
to both sides :)
OpenStudy (anonymous):
you have one side -5y + 2 and another side -6y+3 add 6y to these both sides :)

yes :)
OpenStudy (anonymous):
first say +6-3 = ?
OpenStudy (anonymous):
3
OpenStudy (anonymous):
12x+3=11x-2
12x-11x=-2-3
x=-5
OpenStudy (anonymous):
well,so you have 12x+3 = 11x - 2
how about add -11x to both sides?because we can cross out 11x then...
