I would use elimination method (because I always use this). Multiplying equation 1 by 4 and equation 2 by 5, then subtracting eq 2 from eq 1. thus getting22y= 22, y=1. then substituting y=1 in eq 1

multiply top equation by 2 multiply bottom by 3 cancel y variable out to solve x

5x + 3y = –7 (multiply by 2) 4x – 2y = –10 (multiply by 3) 10x + 6y = 14 12x  6y = 30 add together cancelling out the y variable giving you 22x = 44 22x / 22 = 44 / 22 x = 2
