A) a÷ 6× 6 ÷ 7 × 7 =8+8 - 9÷ 9

B) 113+(113×8)=2000-y+y÷y

(h÷5-5)×9+186÷6=400÷10

(h:5-5)*9+186:6=400:10
(h:5-5)*9+31=40
h:5-5=(40-31):9
h:5=9:9+5. h=6*5
h=30

A) a:6x6:7x7=8+8-9:9
     a:6x6=a
     a:7x7=a
      a=16-1
      a 15
B) 113+(113x8)=2000-y+1
    113x1+113x8=2000-y+1 
     113x9 =2000-y+1
    1017 =2000-y+1/+y
1017+y=2001/-1017
    y=984
