3(5x+2)=8x+20

15x+6=8x+20

15x-8x=20-6

7x=14

then you divide both sides by 2

The answer is 2.

<span>3(5x + 2)=8x + 20
Use distributive property
15x + 6=8x + 20
Subtract 8x from 15x so that the variable x is only on one side.
7x + 6= 20
Subtract 6 from both sides
7x = 14
Divide 7 on both sides so that the only thing remaining on the left side is the variable x.
Final Answer: x= 2</span>
