3(8 - 4x) = 12<br><br> Please help. You have to use distributive property to solve.
____ [38]

Answer:

x=1

Step-by-step explanation:

First, we distribute the 3 to the 8 and the 4x.

Now we have 24-12x=12

Then, we subtract 24 from 12

Now we have -12x=-12

Finally, we devide -12 by -12

Now we have x=1

Hope that helps!
