If you wanted to eliminate the y variable by adding the two equations in the following system, what could be your first step? 5x − 6y = 6 x − y = 12 @jim_thompson5910 some one please help

OpenStudy (anonymous):

Multiply the second equation by 6.

jimthompson5910 (jim_thompson5910):

-6 actually because you want the -1y to turn into +6y

Oh yes, sorry I forgot about the sign! Thanks
