You add all of them up and then do decided by 10 because there are 10 number in there it’s 10.1
The number three (3) when decreased by fifteen (15) is four (4) times its opposite.
In this exercise, you're required to solve for an unknown number by using a variable to represent the number in relation to the known variables (constants) and representing it as an algebraic expression.
Translating the word problem into an algebraic expression, we have;

Rearranging the algebraic expression by (collecting like terms), we have;

Dividing both sides by 5, we have;

<em>x = 3</em>
<em>Therefore, number </em><em>three</em><em> </em><em>(3) </em><em>when </em><em>decreased</em><em> by </em><em>fifteen (15)</em><em> is </em><em>four (4) </em><em>times its </em><em>opposite.</em>
