3x + 7 = 6x - 2 Rearranging gives 6x - 3x = 7 + 2 3x = 9 x = 3
If: 15+3x = 6x-2 Then: 15+2 = 6x-3x => 17 = 3x Therefore: x = 17/3 or 5 and 2/3 as a mixed number
It is: 2-3x simplified
5x^2 + 6x + 9 + (?) = -x^2 +3x + 3 (?) = -5x^2 -6x - 9 -x^2 +3x + 3 = -6x^2 -3x -6 Ans: -6x squared +3x -6
6x-3x =6 3x=6 so 6 divided by 3 = 2
