I have worked this problem out and just need confirmation. 15 + 2x  5 = 130;
2x + 10  10 = 130 10;
2x/2x = 120/2x;
x = 60.

SO SORRY. PLEASE DISREGARD THE FIRST PROBLEM. I DID NOT POST THE ORIGINAL MATH PROBLEM. THIS IS THE ORIGINAL MATH PROBLEM 5 (3+4X) 5 = 130; 15+20x 5 =130;
20x +10 = 130;
20x +1010 = 130 10
20x/20x = 120/20x
x = 6
Thank you 
6 is correct. However, your last step is not quite correct.
starting with...
20x + 10  10 = 130  10
20x = 120
Now divide both sides by 20, not 20x
20x/20 = 120/20
x = 6 
Thank you! I had thought something was wrong with the last step but could not figure it out. You were a great help!

You're welcome.
Glad to help
