Question

the sum of two consecutive even numbers is 86. find the numbers.

Answer 1

$let \: one \: no \: is \: x$
then other is
$x + 2$
sum is
$x + (x + 2) = 86$
or
x= 42
therefore,
first no. is 42
and second is 44

Answer 2

Let the even consecutive be 2x and 2x+2 Then 2x+2x+2=86 4x=84 x=21 Therefore first number 2x=21×2=42 Second number=2x+2=2×21+2=42+2=44
