X= a number
29 - 2x= 21
subtract 29 from both sides
-2x= -8
divide both sides by -2
x= 4
CHECK:
29 - 2x= 21
29 - 2(4)= 21
29 - 8= 21
21= 21
ANSWER: The number is 4.
Hope this helps! :)
You would subtract 1-1/4-1/3
you could find all the multiples of both 3 and 4 and see which one matches 12/12-3/12-4/12
then you would subtract and it becomes 5/12
