c){[(205:5+362:2)-32×6+a]×221:13}-140:5=635
{[41+181)-192+a]×17}-28=635 /+28
(222-192+a)×17=663 /:17
30+a=39 a=39-30 a=9
d)[(30+226:2+a:4):29+20×100]:5-11×6-5×67=0
[(30+113+a:4):29+2000]:5-66-335=0 /+355
[(143+a:4):29+2000]:5-66=355 /+66
[(143+a:4):29+2000]:5=421 /×5
(143+a:4):29+2000=2105 /-2000
(143+a:4):29=105 /×29
