Question

When 5 times a number is decreased by 20, the answer is the same as when 60 increased by that number. Find the number.

Answer 1

20

Explanation:

Answer:

The number is 20.

Explanation:

* Let the 'number' be "x"

* five times a number means "5x"

* decreased by 20 means you are going to use subtraction or minus sign so we have " - 20 "

* increased by means addition

So we have,

5x-20=60+x

Transpose "+x" to the left, and "-20" to the right.

NOTE: When transposing, you change its signs.

So we get,

5x-x=60+20

4x=80

divide both sides of the equation by 4,

So we get,

x=20
