Find the number:

25 more than five times the quantity of a number decreased by 7 is 0.

Asked by Cassidygriffin

Answer (3)

Write an equation, then solve it, where the number is expressed as x. The wording is a little tricky, but I take it as meaning:
-take 7 from the number -multiply it by 5 -add 25
5(x - 7) + 25 = 0 5x - 35 + 25 = 0 5x - 10 = 0 5x = 10 x = 2

The given phrase can be represented by the equation 5(x-7) + 25 = 0. Once you simplify it and isolate x, you will find that the **number **is 2. ;

To find the number, we set up the equation 5 ( x − 7 ) + 25 = 0 and solved it, resulting in x = 2 . This means the number is 2. The verbal description was carefully translated into a mathematical expression before solving it.
