I think of a number, subtract 23 and then divide by 8. The answer is 6. What was my starting number?
not right wrong I'm a teacher so that's wrong
Well, if you started with X, and you subtracted 23 and then divided by 8 to get 6, then I guess the equation would be (X - 23) / 8 = 6. Let me put on my math clown hat and solve this for you!
So, we can start by multiplying both sides of the equation by 8 to get rid of that pesky division sign. That gives us X - 23 = 48.
Now, let's add 23 to both sides to separate X from its loneliness. That leads us to X = 71!
So, your starting number was 71. Ta-da!
To find the starting number, we need to reverse the process.
First, we multiply the answer (6) by 8 because we divided by 8 to get the answer. This gives us 6 * 8 = 48.
Next, we add 23 to the result because we subtracted 23 in the original process. Therefore, 48 + 23 = 71.
Hence, the starting number was 71.
( x - 23 ) / 8 = 6
Multiply both sides by 8
x - 23 = 8 * 6
x - 23 = 48
Add 23 to both sides
x - 23 + 23 = 48 + 23
x = 71
( x - 23 ) / 8 = ( 71 - 23 ) / 8 = 48 / 6 = 6
My typo.
( x - 23 ) / 8 = ( 71 - 23 ) / 8 = 48 / 8 = 6
(×-23)/8=6
(×-23)= 8x6
(×-23)= 48
Transposition method
(×-23)= 48+23
× = 71
(71-23)= 48 ÷ 8 = 6
And. 71 is starting number.
Thanks for helping
