4X - 7 = 31 add 7 to each side 4X - 7 + 7 = 31 + 7 4X = 38 divide both sides integers by 4 (4/4)X = 38/4 X = 38/4 = 19/2 --------------------------reduced, check in original equation 4(19/2) - 7 = 31 76/2 - 7 = 31 38 - 7 = 31 31 = 31 -----------checks
4x+7=9x+7 -5x=0 x=0
- X + 5Y - 4X + 7 gather terms - X - 4X ( same as - X + (- 4X ) 5Y 7 = - 5X + 5Y + 7 ----------------
4x plus 7 plus 3x equals 19 plus xx = 2
4x+7-8x=17-4x+7=17-4x=10x = -5/2
