Question 1021023: what is the final value of x when
x subtract 6, multiply this by 6, add 6, then multiply by 1/6
Answer by Theo(13342)   (Show Source):
You can put this solution on YOUR website! x subtract 6, multiply this by 6, add 6, then multiply by 1/6.
x subtract 6 means x - 6.
multiply that by 6 means 6 * (x-6).
add 6 to that means 6 * (x-6) + 6.
then multiply by 1/6 means (6 * (x-6) + 6) * 1/6.
you would first resolve the most inner set of parentheses to get:
(6x - 6*6 + 6) * 1/6.
simplify to get:
(6x - 36 + 6) * 1/6.
combine like terms to get:
(6x - 30) * 1/6.
resolve the remaining set of parentheses to get:
x - 5.
you can confirm by assuming x is equal to any number you guess at random.
i guessed 100.
your final expression tells you that, when x = 100, x = 100 - 5 = 95.
your original expression tells you that, when x = 100, x subtract 6, multiply this by 6, add 6, then multiply by 1/6 becomes 100 subtract 6, multiply this by 6, add 6, then multiply by 1/6.
100 subtract 6 becomes 94.
multiply that by 6 becomes 564.
add 6 to that becomes 570.
multiply that by 1/6 becomes 95.
it works.
your original expression is x subtract 6, multiply this by 6, add 6, then multiply by 1/6.
your final expression is x - 5.
