X is the amount of distilled water that must be added (in milliliters)
2/(100+x)=9/(1000)
2000=900+9x
1100=9x
122.22=x
x= 122
The answer is 122 milliliters of distilled water must be added

-4(-3x - 8) - 4x + 8 = -8x + 40

Andrew [12]

First we expand and combine the terms on the left side. This gives us

12x + 32 -4x + 8 = -8x + 40

8x + 40 = -8x + 40. Because the two sides cancel each other out when you try and bring all the x to one side, the answer is x = 0.
