4x plus 7 plus 3x equals 19 plus xx = 2
4x+7=9x+7 -5x=0 x=0
3x + 7 = -4x + 28 implies 7x + 7 = 28
4x+7-8x=17-4x+7=17-4x=10x = -5/2
4x - 7 = 2x + 15 4x = 2x +222x = 22x = 11
4x plus 7 plus 3x equals 19 plus xx = 2
If: 5x = 4x+7 Then: 5x-4x = 7 And: x = 7
3x+7=4x 7=4x-3x 7=x
4x+7=9x+7 -5x=0 x=0
3x + 7 = -4x + 28 implies 7x + 7 = 28
4x+7-8x=17-4x+7=17-4x=10x = -5/2
4x + 7 = 6x -7 14=2x so x = 7 (plus a negative # is simply - that number)
= 3
If 4x + 7 = 3... then x must equal -1
4x - 7 = 2x + 15 4x = 2x +222x = 22x = 11
4x + 7 - 8x = 17-4x + 7 = 17-4x = 24x = -6
