z−4/9−1/3=5/9
Step 1: Simplify both sides of the equation.
z−4/9−1/3=5/9
Simplify:
z+−4/9+−1/3=5/9
(z)+(−4/9+−1/3)=5/9(Combine Like Terms)
z+−7/9=5/9
z+−7/9=5/9
Step 2: Add 7/9 to both sides.
z+−7/9+7/9=5/9+7/9
z=4/3
Answer:
z=4/3 or 1 1/3

Solve for z.z−4/9−1/3=5/9
as you know 1/3 = 3/9
rewrite
z - 4/9 - 3/9 = 5/9
z - (4/9 + 3/9) = 5/9
z - 7/9 = 5/9
add both sides to 7/9:
z - 7/9 + 7/9 = 5/9 + 7/9
simplify
z = 12/9
z = 1 3/9
