$$\Huge a(b+c)=ab+ac$$

OpenStudy (skullpatrol):
See how the "a" distributes over the "b" and the "c"?
This is important to really learn and understand

distribute the "15" and the "13" please
OpenStudy (azionne):
30-15x=39-13x
OpenStudy (skullpatrol):
Excellent! Good work.
Now, subtract 30 from BOTH sides.
OpenStudy (azionne):
-15x=9-13x
OpenStudy (skullpatrol):
Next, add 13x to BOTH sides.

OpenStudy (azionne):

OpenStudy (skullpatrol):
