Answer 1

$a+b=311 \\ \\ a:b=7\ \ rest\ \ 15=>a=7b+15 \\ \\ 7b+15+b=311 \\ 8b+15=311 \\ 8b=296 \\ \\ \boxed{b=37} \\ \\ a=7*37+15 \\ \\ \boxed{a=274}$

Answer 2

$a+b=311 \\ a:b=7 \ rest \ 15 \to a=7b+15 \\ \\ 7b+15+b=311 \\8b+15=311 \\8b=311-15 \\ 8b=296 \\\boxed{b=37} \\\\ a+37=311 \\ \boxed{a=274}$
