How do I start this? What steps are first in doing this problem?

3x = 5 + 2(3 + 4x)
 
A good first step would be to multiply out the parentheses on the right-hand side, and simplify.

Then subtract "8x" from either side. Simplify.

Then divide through by "-5".

If you get stuck, please reply showing how far you have gotten in following the above instructions. Thank you.

stapel~we got this far:

3x= 5+2(3+4x)



3x=5+6+8x

-5x= 5=6

-5x = 11

x=6

what's next ????

-5x = 11
Look at this step again. To get x by itself you need to divide both sides by -5.

Ne'mind. Soroban completed the assignment for them in one of their other posts of this exercise.
