2/3a - 2= 1/3
add 2 to both sides
2/3a= 2 1/3
change mixed fraction to improper
2/3a= 7/3
divide both sides by 2/3
a= 7/3 รท 2/3
to divide fraction, multiply by reciprocal (inverse)
a= 7/3 * 3/2
a= (7*3)/(3*2)
a= 21/6
reduce by 3
a= 7/2 OR 3 1/2

ANSWER: 7/2 OR 3 1/2

Hope this helps! :)

2/3a - 2 = 1/3
2/3a = 2 + 1/3
2/3a = 7/3
a = (7/3) / (2/3)
a = (7/3) * (3/2)
a = 21/6
a = 7/2 ---- that is the answer

Hope this helps!
