8 – {3x + 9y – (2x – y) + 8x + 5y}? First change the signs on the terms inside the parentheses, then remove the parentheses.

8 – {3x + 9y + (-2x + y) + 8x + 5y}

8 – {3x + 9y -2x + y + 8x + 5y} combine like terms inside the brackets

8- { 3x -2x +8x +9y +y +5y}

8- {9x + 15y} Now pull out a 3 because 3 goes evenly into 9 and 15 then move 8 to the back of the equation.

-3{3x +5y} +8

8-[3x+9y-(2x-y)+8x+5y] first, distribute the unfavorable sign to the interior parentheses 8-[3x+9y-2x+y+8x+5y] now distribute the unfavorable sign to the brackets 8 - 3x -9y + 2x - y -8x - 5y combine like words (constants, x's, y's) 8 -9x - 15y wish that facilitates!

8 – {3x + 9y – (2x – y) + 8x + 5y}

here is one way to do the problem

8 – {3x + 9y – 2x + y + 8x + 5y}

8 – 3x - 9y + 2x - y - 8x - 5y

8 -9x -15y
