Answer 1

32:8+3×[60+8×(360:a-82:4)]=712
4+3×[60+8×(360:a-20,5)]=712
3×[60+8×(360:a-20,5)]=712-4
3×[60+8×(360:a-20,5)]=708
[60+8×(360:a-20,5)]=708:3
60+8×(360:a-20,5)=236
8×(360:a-20,5)=236-60
8×(360:a-20,5)=236-60
360:a-20,5=176:8
360:a-20,5=22
360:a=22+20,5
360:a=42,5
a=360:42,5
a=3600/425=144/17

3+10×[181×2-2×5×(24+24:a)]=623
10×[362-10×(24+24:a)]=623-3
10×[362-10×(24+24:a)]=620
362-10×(24+24:a)=62
-10×(24+24:a)=62-362
10×(24+24:a)=300
24+24:a=30
24:a=30-24
24:a=6
a=4
