8 – {3x + 9y – (2x – y) + 8x + 5y} ... Start with the given equation.


8 – {3x + 9y -2x + y + 8x + 5y} ... Distribute the negative. So -%282x+-+y%29 becomes -2x%2By


8 – {9x + 15y} ... Combine like terms


8 –9x - 15y ... Distribute the negative. So -%289x+%2B+15y%29 becomes -9x+-+15y


-9x - 15y + 8 ... Rearrange the terms.


============================================
Answer:

So 8 – {3x + 9y – (2x – y) + 8x + 5y} = -9x - 15y + 8
