Question #d4fc2 Prealgebra 1 Answer Saphire · Anirudh E. · Meave60 Dec 14, 2017 If 2a+a=18, then what is the value of a? Explanation: First step is to add the the a's together. In result you get 3a=18. Then you divide by 3 on both sides. The 3s on the left side cancel out, and on the other side you get 6. So you get a=6. Ta da! You're done! I hope that helps!
