When using elimination to solve 2x-3y = 4 7x+ 6y = -1 what would be a possible ﬁrst step? A 4x – 6y = 8 7x + 6y = -l B x = 3/2y + 2 7x + 6y = -1 C 2x -3y = 4 x = -6/7y – 1/7 D y = 2/3x – 4/3 7x + 6y = -1

A because you have to multiply the problems to even in out
(2x-3y=4) x2
(7x+6y=-1) x1

4x – 6y = 8
7x + 6y = -l
