Simple,its just like this: 6x+1+7-3 =6x+8-3 =6x+5
6x+7 = -56x = -12x = -2
If: 9x+7 = 6x+25 Then: x = 6
55 = 6x + 7 so 48 = 6x so 8 = x
6x-4+7=-5 6x+3=-5 6x=-8 x=-8/6 = -4/3
7+10+(-6x)=17-6x
7x + 7 + 6x - 9 = 13x - 2
4x + 7 = 6x -7 14=2x so x = 7 (plus a negative # is simply - that number)

-6x+3 = -7-5x 7+3 = 6x-5x 10=x
55 = 6x + 7 so 48 = 6x so 8 = x
xx+3x+7=6x+18 xx+3x+7-(6x+18)=6x+18-(6x+18) xx-3x-11=0 Factors of -11: 1,-11 -1,11 Doesn't factor evenly, use quadratic
x2+6x-7 = (x+7)(x-1) when factored
6x-4+7=-5 6x+3=-5 6x=-8 x=-8/6 = -4/3
10x + 7 = 4x + 49 6x + 7 = 49 6x = 42 x = 6
