make x the subject of a+x=b

OpenStudy (lgbasallote):

do you have an idea what you will do?

OpenStudy (anonymous):

not a one

OpenStudy (lgbasallote):

if you have something like x + 1 = 0 do you know how you can isolate x?

OpenStudy (anonymous):

subtract 1 from both sides. x=1

OpenStudy (anonymous):

-1

OpenStudy (lgbasallote):

right... so if you have a + x = b what would you do?

OpenStudy (anonymous):

to isolate x? subtract a from both sides?

OpenStudy (lgbasallote):

correct. and how will your equation look like if you subtract a?

OpenStudy (anonymous):

x=b-a

OpenStudy (lgbasallote):

correct. that's the answer

OpenStudy (anonymous):

really? thats all i have to do? i feel dumb

OpenStudy (lgbasallote):

haha lol. people do get confused when everything are letters =)) you just have to look at them like numbers to make it easier

OpenStudy (anonymous):

makes sense. thank you so much would that also work for division? e.g az=b/c

OpenStudy (lgbasallote):

yep. you just isolate whichever is being asked to "make the subject"

OpenStudy (anonymous):

omg. fml
