1=%281%2F3%29a-5 Start with the given equation



%283%29%281%29=%283%29%28%281%2F3%29a-5%29 Multiply both sides by the LCM of 3. This will eliminate the fractions (note: if you need help with finding the LCM, check out this solver)



3=a-15 Distribute and multiply the LCM to each side



0=a-15-3Subtract 3 from both sides


-a=-15-3 Subtract a from both sides


-a=-18 Combine like terms on the right side


a=%28-18%29%2F%28-1%29 Divide both sides by -1 to isolate a



a=18 Divide

Answer:
So our answer is a=18
