If then, we isolate the 1/3a. Since 5 is being subtracted on left side, we use the opposite operation of Subtraction.

here is how to do this problem the right way. 1 = 1/3a - 5, first we are solving for A so we take the and subtract 1 from both sides that gives =1/3a-5-1 next add the two negative numbers together to get -6 so now we have =1/3a-6 next divide by 1/3 so now we have A=-6/1/3
