To solve for 'a', we need to isolate it on one side of the equation.
First, we'll start by getting rid of the fraction on the left side of the equation by multiplying both sides by the denominator, which is 9:
20 + 2/9 a = 38
9(20 + 2/9 a) = 9(38)
180 + 2a = 342
Next, we'll isolate the 'a' term by subtracting 180 from both sides:
2a = 342 - 180
2a = 162
Finally, we'll solve for 'a' by dividing both sides by 2:
a = 81
20+2/9a=38
