Question

if the sum of two no is -7. if one of them is -11/6 and the other no is
a. -5/6
b. 77/42
c. -31/6
d. 14​

Answer 1

GIVEN:

• Sum of two numbers = –7
• One number = –11/6

TO FIND:

• What is the other number ?

SOLUTION:

Let one number be 'y'

• y = –11/6

and

Another number be 'x'

We have given that, sum of two no is -7

• 【One number + another number = –7 】
• x + y = –7

According to question:-

$\sf{\hookrightarrow x + y = -7 }$

$\sf{\hookrightarrow x + \bigg(\dfrac{-11}{6} \bigg) = -7 }$

$\sf{\hookrightarrow x - \dfrac{11}{6} = -7}$

$\sf{\hookrightarrow \dfrac{6x -11}{6} = -7 }$

$\sf{\hookrightarrow 6x -11 = 6 \times -7}$

$\sf{\hookrightarrow 6x -11 = -42 }$

$\sf{\hookrightarrow 6x = -42 +11 }$

$\sf{\hookrightarrow 6x = -31 }$

$\bf{\hookrightarrow x = \dfrac{-31}{6} }$

❝ Hence, the another number is –31/6 ❞

Answer 2

$\huge\underline\bold\red{Answer}$

Given :-

• Sum of two numbers is -7

• One of them is -116

To Find

• The other number

__________________________

Let the other number be 'x'

Then,

x + (-11/6) = - 7

=> x - 11/6 = - 7

=> (6x - 11) / 6 = - 7

=> 6x - 11 = - 42

=> 6x = - 42 + 11

=> 6x = - 31

=> x = - 31/6

Hence, the other number is - 31/6
