Answer:
z= 4/3
Explanation:
To solve z - 4/9 - 1/3 = 5/9 first we observe that two of the fractions have 9 as a denominator and one has 3 as a denominator. So we can transform 1/3 into a fraction with denominator equal to 9.
We do this by multiplying both numerator and denominator by 3 and we get.

Now our expression is z - 4/9 - 3/9 = 5/9
To solve for z we need to take all the terms but the z to the right side with the opposite sign and sum up those terms.

Thus, z = 4/3
