Question

936+n-(1205+376)=2128 ;

(99-b-3·8)+2·6:2=8·2+5·10

Answer 1

(99-b-24)+12:2=66
(99-b-24)+12=66*2
(99-b-24)+12=132
99-b-24=120
99-b=120+24
99-b=144
-b=144+99
-b=243
b=-243

Answer 2

936+n-1581=2128
n-1581=2128-936
n-1581=1192
n=1192+1581
n=2773
(99-b-24)+2*3=16+50
75-b+6=66
75-b=66-6
75-b=60
b=75-60
b=15
