he sum of a number and 4 divided by 2 is 5

Answer 1

"the sum of a number and 4 divided by 2 is 5":

"a number": x

"the sum of a number and 4": (x + 4)

"... divided by 2": (x + 4) / 2

"... is 5": (x + 4) / 2 = 5

So we solve for x:

(x+4)/2 = 5

*2 *2

x+4 = 10

-4 -4

x = 6

So, the number we are looking for is 6.
