-5y+2=-6y+3

OpenStudy (anonymous):

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 :)

OpenStudy (anonymous):

do i add the 5 and 2 together then add 6?

OpenStudy (anonymous):

-5y+6y=3-2 y=1

OpenStudy (anonymous):

no it isn't nessesary ... and add 6y not 6!

OpenStudy (anonymous):

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...

OpenStudy (anonymous):

-11x + 12x + 3 = 11x -2 -11x

OpenStudy (anonymous):

i added -11x

OpenStudy (anonymous):

we can add anything to the both sides of an equation.... got it?
