Let x be the number you dont know. The difference between twelve and the product of five and a number is the same as writing: 12 – 5x. And you knwo that equals 7. So 12 – 5x = 7 and solve this for x to get your answer.

well, here we have:
12 – 5x = 7
-5x = 7 – 12
-5x = -5
x = 1
lets check:
12 -5(1) = 7
12 – 5 = 7
7 = 7
looks good to me

Set it up this way.
12 – 5n = 7
-5n = 7 – 12
-5n = -5
so 5n = 5
n = 1
When you plug 1 back into the first equation it checks out.
