Answer: a = 22
Step-by-step explanation: First isolate a/3 by adding 7 to both sides of the equation. That gives you a/3 = 22.
From here since <em>a</em> is being divided by 3, multiply both sides of the equation by 3 so <em>a</em> <em>= 66</em>. We can check our answer by substituting a 66 back in for <em>a</em> in the original equation and we have or 22 - 7 = 15 or 15 = 15. Since this is a true statement, our answer checks.
