To determine which equations have solutions z=3, we can substitute z=3 into each equation and see if the equation is true.
For the first equation, 54-8z=30:
Substituting z=3 gives 54-8(3)=30, which simplifies to 54-24=30. This is not a true statement, so z=3 is not a solution to this equation.
For the second equation, 9z-5=22:
Substituting z=3 gives 9(3)-5=22, which simplifies to 27-5=22. This is also not a true statement, so z=3 is not a solution to this equation.
For the third equation, 9z+22=26:
Substituting z=3 gives 9(3)+22=26, which simplifies to 27+22=26. This is not a true statement, so z=3 is not a solution to this equation.
For the fourth equation, 5z+40=62:
Substituting z=3 gives 5(3)+40=62, which simplifies to 15+40=62. This is not a true statement, so z=3 is not a solution to this equation.
Therefore, none of the given equations have solutions that are z=3.
