Given that, I thought of a number, doubled it, and then decreased it by 17. Then I divided the result by 3. I got 15.
What is the equation?
In mathematics, an equation is a formula that expresses the equality of two expressions, by connecting them with the equals sign =.
Let the number be x.
Double it=2x
Decreased it by 17=2x+17
Divided the result by 3=(2x+17)/3
The result is equal to 15.
(2x+17)/3=15
