Question

Sum of two integers is 20 , if one of them is -2 then find the value of the other.​

Answer 1

Answer:

the other is -18

Step-by-step explanation:

-18 + -2 =20

Answer 2

Answer:

Given:-

Sum of two integers is 20, if one of them is -2 then find the value of the other.

To Find:-

The other number.

Note:-

●》Here question tells that, -2 + other number gives 20.

●》For finding variables, constant needs to rearranged from its side to another and signs are also changed or not. For example - negative becomes positive ( signs are changed ).

●》Equation is that both side calculations should be equal.

Solution:-

$\huge\red{First \ \ number = -2, Other \ \ number = ?, Let \ \ it \ \ be \ \ "x"}$

☆ According to note first point, equation~

▪︎$-2 + x = 20$

☆ According to note second point ( rearrangement )~

▪︎$x = 20 + 2$

☆ After doing calculations~

▪︎$x = 22$

$\huge\pink{x = 22}$

Checking:-

♤ Let's check accordingly to note third point ( equation )~

• $-2 + x = 20 \ \ ?$

• $-2 + 22 = 20 \ \ ?$

• $22 - 2 = 20 \ \ ?$

• $20 = 20 \ \ ?$

♤ Yes!

$\huge\red{Hence, Proved \ \ that \ \ x = 22}$

Answer:-

Hence, the other number = 22.
