Answer 1

Answer:

6/7 should be added to -5/7 to get 1/7

Answer 2

$\bigstar\sf\underline\pink{let \:x \:be \:the \:number \:which\: is \:added\: to \dfrac{-5}{7}\: to\: get \:\dfrac {1}{7}}$

⠀

$\longrightarrow\sf{To \:find\: the\: value\: of \:x}$

$\longrightarrow\sf{\dfrac{ - 5}{7} + x = \dfrac{1}{17} }$

$\longrightarrow\sf{\dfrac{ -5 + 7x }{7} = \dfrac{1}{17} }$

$\longrightarrow\sf{17 (-5 + 7x) = 7}$

$\longrightarrow\sf{- 85 + 119x = 7}$

$\longrightarrow\sf{119x = 7 + 85}$

$\longrightarrow\sf{119x = 92}$

⠀

$\longrightarrow\sf\orange{x = \dfrac{92}{119}}$
