Question

What does 9+2x=25 mean

Answer 1

You need to solve for x. This is how you do it:

$9 + 2x = 25$                      subtract 9 to both sides
$2x = 25 - 9$                       subtract 25 and 9
$x = 16/2$                           divide 2 to both sides
$x = 8$

Answer 2

9+2x=25=>2x=25-9=>2x=16=>x=16:2=>x=8........ Prob:9+2*8=9+16=25
