Question

If the sum of two consecutive numbers is 43 , find these two numbers.

Answer 1

Suppose, the first number is x
$\therefore$ The second consecutive number is x+1
the total of these consecutive number x+(x+1)is 43
$x+(x+1)=43$
$2x+1=43$
$2x=43-1$
$2x=42$
$x=\frac{42}{2}$
$\therefore x=21$
Therefore, the number is 21. and the second consecutive number $x+1=21+1=22$
