To determine if z=3 is a solution for each equation, we substitute z=3 into each equation:

54 - 8(3) = 30
5(3) + 40 = 62
9(3) - 5 = 22
9(3) + 22 = 26

Simplifying each equation:

54 - 24 = 30
15 + 40 = 62
27 - 5 = 22
27 + 22 = 26

The second equation is the only one that is true when z=3:

15 + 40 = 62

Therefore, the equation 5z + 40 = 62 has a solution z=3.
