Answer:
20
Step-by-step explanation:
Answer:
The number is 20.
Step-by-step 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
