Answer:
4
Step-by-step explanation:
We can actually make the two equal each other like so:
3d-4=12d/6
Multiply both sides by 6:
18d-24=12d
Add 24 to both sides:
18d=12d+24
Subtract 12d from both sides:
6d=24
Divide by 6:
d=4

Answer:
c) The given expression represents Addition Property of Equality.
Step-by-step explanation:
Here, the given expression is j = k
Now by ADDITION PROPERTY OF EQUALITY:
The property that states that if you add the same number to both sides of an equation, the sides remain equal.
So, <u> if A = B ⇒ A + </u><u>x </u><u> = B + </u><u>x</u>
<u></u>
Now, here given that j = k
If we add the same number 9 on both the sides, the equation remains undisturbed.
⇒ j + 9 = k + 9
Hence, the above expression represents Addition Property of Equality.
