simplify the first equation by dividing each term by 3 then multiply each term by +2 add equations solve for y
OpenStudy (campbell_st):
3x - 6y = 12 (1) -2x + 3x = 6 (2) multiply equation (2) by 3 and equation (1) by 2 and add to eliminate x 6x - 12y = 24 -6x + 9y = 18 -------------- then solve for y
OpenStudy (anonymous):
y = 2 ?
OpenStudy (campbell_st):
well adding the equations gives -3y = 42 solve for y
OpenStudy (anonymous):
y = 14
