85

Explanation:

Given,


{ \pink{ \sf{h(x) = 1 - 7x}}} \: { \to} \: { \tt{eq}^(n) (1)}

Put x = 9 in Eqⁿ (1)


{ \pink{ \sf{h(9) = 1 - 7(9)}}}


{ \pink{ \sf{h(9) = 1 - 63}}}


{ \red{ \boxed{ \pink{ \sf{h(9) = - 62}}}}}

Let


{ \green{ \sf{23 - h(9)}}} \: { \to} \: { \tt{ {eq}^(n) (2)}}

Substitute the value of h(9) in Eqⁿ (2)


{ \green{ \sf{23 - ( - 62)}}}


{ \green{ \sf{23 + 62}}}


= { \pink{ \boxed{ \red{ \sf{85}}}}}
