Question

aflati nr necunoscut 100-2*[(b;4-100);4+14]=60

Answer 1

100-2x[(b:4-100):4+14]=60
2x[(b:4-100):4+14]=100-60
2x[(b:4-100):4+14]=40
(b:4-100):4+14=40:2
(b:4-100):4+14=20
(b:4-100):4=20-14
(b:4-100):4=6
b:4-100=6x4
b:4-100=24
b:4=24+100
b:4=124
b=124x4
b=496

Answer 2

100-2[(b:4-100):4+14]=60
100-2[(b/4-400/4):4+14]=60
100-2[((b-400)/4)/4+14]=60
100-2[(224/16)+(b-400)/16]=60
100-2[(b-400+224)/16]=60
100-[2(b+(224-400))]/16=60
100-(b-176)/8=60
800/8+(176-b)/8=60
[(800+176)-b]/8=60
(976-b)/8=60
976-b=8*60
976-b=480
b=976-480
b=496
