Question

13-3[ 3(x+2)+4 ] = 11-[ 6(-2x-2)+1 ]

13-3-[ 3(x+2)+4 ] = 11-[ 6(-2x-2)+1 ]

Answer 1

13-3[ 3(x+2)+4 ] = 11-[ 6(-2x-2)+1 ]
13-3[3x+6+4]=11-[-12x-12+1]
13-9x-18-12=11+12x+12-1
-9x-12x=11+12-1+18-13
-21x=27
x=27/-21
x= -9/7

Answer 2

13-3[3(x+2)+4]=11-[6(-2x-2)+1]
13-3[3x+6+4]=11-[-12x-12+1]
13-3[3x+10]=11-[-12x-11]
13-9x-30=11+12x+11
-9x-17=22+12x
-17-22=12x+9x
     -39=21x
  -39/21 =x
  -13/7=x


13-3-[3(x+2)+4]=11-[6(-2x-2)+1]
13-3-[3x+6+4]=11-[-12x-12+1]
13-3-[3x+10]=11-[-12x-11]
13-3-3x-10=11+12x+11
           0-3x=22+12X
            -22=12X+3X
            -22=15X
        -22/15=X
