Question

[(30+226:2+x:4):20+20x100]:5-11x6-5x6-5-67=0

Answer 1

[(30+226÷2+x÷4):20+20x100]÷5-11×6-5×6-5-67=0
[(30+113+x÷4)÷20+2000]÷5-66-30-5-67=0
[(143+x÷4)÷20+2000]÷5-168=0
[(143+x÷4)÷20+2000]÷5=168
(143+x÷4)÷20+2000=168×5
(143+x÷4)÷20=840- 2000
(143+x÷4)÷20= -1160
(143+x÷4)= -1160×20
143+x÷4= -23200
x÷4=-23200-143
x= -23343×4
x= -93372

Answer 2

[(30+226:2+x:4):20+20x100]:5-11x6-5x6-5-67=0
[(30+113+x:4):20+2000]:5-66-30-5-67=0
[(30+113+x:4):20+2000]:5=66+30+5+67
[(143+x:4):20+2000]:5=168
(143+x:4):20+2000=168x5
(143+x:4):20+2000=840
(143+x:4):20=840-2000
(143+x:4):20=-1160
(143+x:4)= - 1160x20
143+x:4= - 23200
x:4=-23200-143
x:4= -23343
x= -23343x4
x= -93372
