369 - [ ( x + 112 ): 5 + 113 ] = 134
369-(x+112/5+113)=134
369-x+112/5-113=134
256-x+112/5=134
1280-(x+112)=670
1280-x-112=670
1168-x=670
-x=670-1168
-x=-498
x=498
104 : [ ( x - 3 x 8 ) x 2 : 8 ) = 13
104:((x-3x8)x2:8)=13, x[tex]\neq[/tex]24
104:((x-24)x2:8)=13
104:(x-24)x2/8=13
104:x-24/4=13
104x 4/x-24=13
416/x-24=13
416=13(x-24)
32=x-24
-x=-24-32
-x=-56
x=56, x[tex]\neq[/tex]24
x=56
