not do all the work for him/her!

Answer 21

@some_someone .....i was not giving just answers i also included the method

Answer 22

@an12345 just follow @physicsboffin's method... you are always just trying to solve by substitution or elimination to isolate one of the variables in one of the given equations. once u find the value of one of the variables, sub that value into the other equation to solve for the OTHER missing variable, and voila! you have your answers haha :P

then you can check to see if you're right by plugging in those values in their respective variables. If both equations work when those values are subbed in, then there you go! you have your answer :)

so that's sort of an explanation via words haha but @physicsboffin showed u exactly how to do it by showing work :)

Answer 23

well it would have helped alot more if you went step-by-step and guide the user....

Answer 24

@physicsboffin good job though :)

Answer 25

@some_someone .....maths is tough for some people....not everyone finds it easy....so i kinda feel bad if i leave them to suffer...

Answer 26

@an12345 just post them one by one and people can explain each one to you more thoroughly :)

Answer 27

Answer 29
