Answer 1

1500- [820 -16 * (125 * a -150) : 80]=700
-820+  16*(125*a-150) : 80=700-1500
-820+16*(125*a-150):80=-800
16*(125*a-150):80=-800+820
16*(125*a-150):80=20
(125*a-150):80=20:16
(125*a-150)=20/16 *80
125*a-150=100
125*a=100+150
125*a=250
a=250/125
a=2

Answer 2

700+1500=2200
2200+820=3020
3020x80=241600
241600:16=15100
15100+150=15250
15250:125=122
a=122
proba:
122x125=15250
15250-150=15100
15100x16=241600
241600:80=3020
3020-820=2200
2200-1500=700
