The sum of two integer is -55 one is 80find the other

Answer 1

ㅤ$\;\;\underline{\textbf{\textsf{ Given:-}}}$

• The sum of two integers is = -55

• One integer is = 80

ㅤ$\;\;\underline{\textbf{\textsf{ To Find :-}}}$

• What's the other integer?

ㅤ$\;\;\underline{\textbf{\textsf{ Solution :-}}}$

Let the unknown integer be x.

Given that,

• The sum of two integers is = -55

$\bf\underline{\green{\:\:\:\:\:\:\:\:A.T.Q:-\:\:\:\:\:\:\:}}$

$\dashrightarrow \sf \: \: \: x + 80= -55$

$\dashrightarrow \sf \: \: \: x = -55-80$

$\dashrightarrow {\boxed{\frak{\purple{x= -135}}}}\;$

ㅤ$\;\;\underline{\textbf{\textsf{ Hence-}}}$

$\underline{\textsf{ The other integer is \textbf{-135}}}.$

Answer 2

$\underline{\green{\bf{Given :-}}}$

• The sum of two integer is - 55
• One is 80

$\underline{\purple{\bf{To \: Find :-}}}$

• The other integer

$\underline{\orange{\bf{Solution :-}}}$

We have,

• The sum of two integer is - 55
• One is 80

Let,

• The other integer be "x"

$\underline{\blue{\bf{A.T.Q :-}}}$

$:\implies\tt{x + 80 = - 55}$

$:\implies\tt{x = - 55 - 80}$

$:\implies\red{\tt{x = - 135}}$

$\underline{\gray{\bf{Verification :-}}}$

We have,

$:\implies\tt{x + 80 = - 55}$

Substituting the value of x,

$:\implies\tt{- 135 + 80 = - 55}$

$:\implies\tt{- 55 = - 55}$
