10x+14y=62

OpenStudy (hba):

There are two methods to solve this 1)Sub 2)Elimination

hartnn (hartnn):

correct, now multiply 2nd equation by 5, what you get ?

OpenStudy (hba):

@hartnn Is showing you elimination :)

OpenStudy (anonymous):

10x+20y=80

hartnn (hartnn):

very good, now subtract the 2 equation which you got.

OpenStudy (anonymous):

-6y=-18

hartnn (hartnn):

good! so, y=.... ?

hartnn (hartnn):

divide both sides by -6

OpenStudy (anonymous):

y=3

hartnn (hartnn):

thats correct :) now put y=3 in any of the equations you want to get 'x'.

hartnn (hartnn):
