Question

Answer 1

Hey

Here is your answer,

Given that,

Sum of two numbers = -6
One number = -7/2
another number = x

So,
X + (-7/2) = -6
X = -6+7/2
X = -12+7/2
X = -5/2

Hope it helps you!

Answer 2

Let the other number be a

According to question,

-7/2 + a = - 6

=> a = - 6 + 7/2

=> a = ( - 12 + 7) / 2

=> a = - 5 /2

Required number = - 5/2
