Let's take the number to be y.

Here, we are told that 2 times a number minus 3 is 15

i.e 2 * y - 3 = 15

Now let's find y:


(2\text{ }\ast\text{ y) - 3 = 15}

To find y, first add 3 to both sides of the equation:


(2\ast\text{ y) - 3 + 3 = 15 + 3}
2\text{ }\ast\text{ y = 18}

Divide both sides of the equation by 2:


\frac{2\text{ }\ast\text{ y}}{2}\text{ = }(18)/(2)
y\text{ = 9}

The value of the number is 9
