Question

The sum of two integers is -15 .if one of numbers is -150, find the other number

Answer 1

☯ GIVEN :

• Sum of the two numbers = -15

• One number = -150

☯TO FIND :

• The other number .

➲SOLUTION :

✞Let the other number be x.

• Sum of the two numbers = -15

$\implies {\sf{ One \:Number+Other \:Number = - 15}}$

$\implies {\sf{ - 150+ x= - 15}}$

• Transposing -150 to RHS

$\implies {\sf{x= - 15 + 150}}$

$\implies \underline{\boxed{\red{\bf{x= 135}}}}$

$\huge{\pink{\therefore}}$The other number is 135.

✞VERIFICATION :

• Sum of the two numbers = -15

$\implies {\sf{ One \:Number+Other \:Number = - 15}}$

$\implies {\sf{ - 150+ 135= - 15}}$

$\implies {\sf{ -15 = - 15}}$

$\implies \underline{\boxed{\red{\bf{LHS = RHS}}}}$

$\huge{\pink{\therefore}}$Verified.
