Hi there! :)
Answer:
d<7
*The answer must have a positive sign and less than symbol sign.*
Step-by-step explanation:
First, you subtract by 12 from both sides of an equation.
[tex]d+12-12<19-12[/tex]
Then, you subtract by the numbers from left to right.
[tex]19-12=7[/tex]
Final answer is d<7
Hope this helps!
Have a nice day! :)
:D
