Question

Set up equation and solve,the sum of two consecutive numbers is 89.find them

Answer 1

Answer:

$\huge\boxed{\fcolorbox{blue}{orange}{HELLO\:MATE}}$

Let us take the first number be x.

Then the second number=x+1

Sum of numbers = x +x + 1

=2x + 1)

But, it is given 89.

So, ATQ, 2x+1 = 89

=> 2x =89 - 1

=> 2x = 88

=> x =88/2

Therefore x = 44

$\large\red{\boxed{First\: number = x = 44.}}$

$\large\purple{\boxed{Second \:number = x+1 =44+1=45}}$

Answer 2

Answer:

first number =x

second number=x+1

sum of the numbers=89

=x+x+1=89

=2x+1=89

=2x=89-1

=2x=88

x=88/2

x=44

first number =44

second number =44+1=45

sum of the numbers =89

44+45=89
