Question 93365
Question:


Write an algebraic equation for the english statement.  "Subtract 5 from the sum of x and 7 times 3 and the result is 20.

I came up with -5+6 = 7x3=20


Answer:


sum of x and 7 = x + 7


  sum of x and 7 times 3 = (x + 7 ) * 3


Subtract 5 from the sum of x and 7 times 3 = (x + 7)3 - 5


Subtract 5 from the sum of x and 7 times 3 and the result is 20 ==>


==> (x + 7)3 - 5 = 20



or you can write, 3 (x + 7)  - 5 = 20 


hope you found the explanation useful.
