x > 5

Explanation:

Please: If possible answers are given, share them.

To solve 12 - X < 7​, add x to both sides, so that x is positive:

12 < x + 7

Now subtract 7 from both sides, to isolate x:

5 < x or x > 5

Answer 2

x > 5

Explanation:

`12 - x < 7`

i) move constants to the right-hand side and change its sign

`- x < 7 - 12`

ii) calculate the difference

`- x < - 5`

iii) change the signs on both sides of the inequality and flip the inequality sign

`x > 5`
