Question

sum of two rational numbers is -6/5 if one of them is -2 find the other

Answer 1

Answer:

the other number is 4/5

Step-by-step explanation:

let the number is x

then

x+(-2) = -6/5

x - 2 = -6/5

x = -6/5 +2

x = (-6 + 10)/5

x = 4/5

Answer 2

Step-by-step explanation:

let the number = x

=> (-2) + x = $\frac{-6}{5}$

=> x = $\frac{-6}{5}$ + 2

=> x = $\frac{ -6 \: + \: 2 }{ 5 }$

=> x = $\frac{-4}{5}$

The other number is $\frac{-4}{5}$

Proof :-

LHS = -2 + $\frac{4}{5}$

• $\frac{-2 \: + \: (-4) }{5}$

• $\frac{ -2 \: -4}{5}$

• $\frac{-6}{5}$ = RHS

Therefore , LHS = RHS
