Question

the sum of two number is -3/4 if one number is -5 what is other ?​

Answer 1

$\huge\underline\mathtt\red{Answer\:}$

Given sum of two numbers=-3/4

One of the two numbers=-5

Let the other number be x

$\large\mathtt\blue{ = > x + ( - 5) = \frac{ - 3}{4} \:}$

$\large\mathtt\blue{ = > x - 5 = \frac{ - 3}{4} \:}$

$\large\mathtt\blue{ = > x = \frac{ - 3}{4} + 5 \:}$

$\large\mathtt\blue{ = > x = \frac{ - 3}{4} + \frac{5}{1} \:}$

Take L.C.M. to make the denominators same.

L.C.M. of 4 and 1=4

$\large\mathtt\blue{ = > \frac{ - 3}{4} \ \times \frac{1}{1} = \frac{ - 3}{4} :}$

$\large\mathtt\blue{ = > \frac{5}{1} \times \frac{4}{4} = \frac{20}{4} \:}$

$\large\mathtt\blue{ = > \frac{ - 3 + 20}{4} \:}$

$\large\mathtt\blue{ = > x = \frac{17}{4} \:}$

So the other number us 17/4

Answer 2

Hii...

Sum of two number = -¾

One number = -5

Other number = x

A.T.Q.

=> x + (-5) = -¾

=> x - 5 = -¾

=> x = -¾ + 5

=> x = 17/4
