9x+6 = 6x+15 9x-6x = 15-6 3x = 9 x = 3
no
this is the same as 6x - 2 = 6x - 2! There are an infinite number of possibilities for "x".
3x + 6y + 6x = 9x + 6y which can be factorised as 3(3x +2y)
You can just add them together. The answer is 9x.
If: 9x+7 = 6x+25 Then: x = 6
6x + 47 = 9x + 11 6x + 36 = 9x 36 = 3x 12 = x
9x + 3 - 6x - 2 = 3x + 1
9x+6 = 6x+15 9x-6x = 15-6 3x = 9 x = 3
no
144
9x-11 = 6x+1 9x-6x = 1+11 3x = 12 x = 4
9x-19=6x+2 so 3x=21 and x=7
3x + 6x +1 = 10 9x = 10 - 1 9x = 9 x = 1
this is the same as 6x - 2 = 6x - 2! There are an infinite number of possibilities for "x".
In this equation, x=6.
6x+5=3x+5 5=9x+5 x=0
