Hey dear ☺️


Here your answer

$suppose \: numbers \: are \: x \: and \: y \\ \\ first \: condition \: given \: that \: them \: sum \: is \: 70 \\ \\ \\ \\ so \\ \\ \\ \\ x + y = 70 \\ \\ \\ second \: condition \: given \: that \: them \: different \: is \: 30 \\ so \\ \\ \\ x - y = 30 \\ \\ \\ \\ \\ solve \: this \: two \: equation \\ \\ \\ \\ \\ x + y = 70 \\ \\ x - y = 30 \\ - - - - - - - \\ 2x = 100 \\ \\ x = 50 \\ \\ so \: y \: = 70 - 50 = 20$
