Question

138+x+57=218;248-(y+123)=24;(24-x)+37=49;169+(87+n)=303

Answer 1

138+Х+57=218 248-(У+123)=24

195+Х=218 248-У-123=24

Х=218-195 У=125-24

Х=23 У=101

138+23+57=218 248-(101+123)=24

218=218 24=24

(24-Х)+37=49 169+(87+n)=303

24-X+37=49 169+87+n=303

61-X=49 256+n=303

X=61-49 n=303-256

X=12 n=47

(24-11)+37=49 169+(87+47)=303

49=49 303=303
