Answer 1

(k:16)*13+11=50
к:16)*13=50-11
(к:16)*13= 39
к:16=39:13
к:16=3
к= 3*16
к=48
(48:16)*13+11= 50
50=50


14-72:(d-3)=8
14-8= 72:(d-3)
6= 72:(d-3)
72:6= в-3
12= d-3
d=12+3
d=15
14-72:(15-3)=8
8=8

 (980:n)*18-84=276
(980:n)*18= 276+84
(980:n)*18=360
980:n=360/18
980/n=20
n= 980/20
n=49
(980/49)*18-84=276
276=276

 96+(80-x):14=100
(80-x)/14= 100-96
(80-x)/14=4
(80-x)=4*14
80-x=56
x=80-56
x=24
96+(80-24)/14=100
100=100
