15x-10=6x(x+2)+(-x+3)

(5-3x)-(-4x+6)=(8x+11)-(3x-6)

3x+[-5x-(x+3)]=8x+(-5x-9)

16x-[3x-(6-9x)]=30x+[-(3x+2)-(x+3)]

Answer 1

15x-10=6x-(x+2)+(-x+3)

15x-10 = 6x-x-2-x+3

15x-10  =4x+1

11x = 11

x=1



3x+[-5x-(x+3)]=8x+(-5x-9)

3x+[-5x-x-3]=8x-5x-9

3x-6x-3 =8x-5x-9

-3x-3 = 3x-9

-3+9 = 3x+3x

6 = 6x

x = 1

 16x-[3x-(6-9x)]=30x+[-(3x+2)-(x+3)]

 16x-[3x-6+9x] =30x+[-3x-2-x-3]

16x-12x+6 = 30x-4x-5

4x+6 = 26x-5

11 = 22x

x= 11/22 = 1/2
