A number is multiplied by 5 and then 3 is subtracted from the product the result is 12 find the number

We can make an equation for this, if we call the number in question x, we know that first we had 5x and then 3 was taken from that to get 12

This gives us 5x - 3 = 12

We can then add 3 on both sides to get 5x = 15

Then we can divide both sides by 5 to get x = 3

So the number was 3

We can set this up as the equation 5x-3=12. Solve to find x, which is 3.
