Question

A4. The sum of two integers is –256. If one of them is 45, find the other.​

Answer 1

Step-by-step explanation:

THEORY

In order to solve this question, we need to take the required data and form a liner expression in one variable and then solve for that variable

GIVEN

We are given that sum if 2 numbers is -256 and we are given one number to be 45.

So now we assume the other number to be X

SOLUTION

So now, with the given date , we will form a linear expression in 1 variable

x + 45 = -256

x = -256 - 45

X = -301

The required number is -301

Answer 2

$\displaystyle\huge\pink{\underline{\underline{Given}}}$

The sum of two integers is - 256 . one of them is 45

$\displaystyle\huge\red{\underline{\underline{To\:Find}}}$

The other unknown integer .

$\displaystyle\huge\purple{\underline{\underline{Solution}}}$

$\implies\:\pink{Let\:the\: unknown\:no.\:be\:x}$

$\implies\:\pink{Now\:by\:this\: statement\:we\:get}$

$\implies\:\pink{The\:linear \: equation}$

$\implies\:x\:+\:45\:\implies\:-\:256$

$\implies\:x\:\implies\:-\:256\:-\:45$

$\implies\:x\:\implies\:-\:301$

$\bf\orange{What\:is\:a\:linear\: equation\:?}$

A equation with its highest power as one is called linear equation .

• Example $\implies$ 2x + 4 = 8

• 45 + 3y = 32

$\bf\green{What\:is\:a\: constant\:and\:a\: variable\:?}$

A constant is a number which has a fixed value .

A variable is a number which has no fixed value and its value is unknown . Variable is also called unknown in mathematics . We generally let the value of a variable as any alphabet while solving equations
