Sagot :
Answer:
-27
Step-by-step explanation:
-Let's take the number we don't know as x
- all we do is substitutein the x which is our unknown number
3 - x / 6 = 5
We want to get rid of the fraction so we have to multiply 5 by 6 which gives us 30
So now we are left with 3 - x = 30
We just want x by itself so we are going to take away 3 from 30 to get rid of the 3 from the x side
-x = 27
We want x as a positive number so we have to multiply -x and 27 by -1
This is because a negative number multiplied by another negative number gives us a positive number.
Remember that whatever we do to the left side,we do the same to the right
-x =27
×-1 ×-1
x=27
Now x is positive we can see that the answer is -27.
This means that the unknown number is -27.
Hope this helped.
