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

12-5x=7

step 1) -5x=7-12

-5x=-5

step 2)x=-5/-5

x=1

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.
