*25 points* an someone pls tell me how many solutions this equation have

Answer:
infinite number of solutions
Step-by-step explanation:
4(z - 5) + 2 = 4z - 18 ← distribute and simplify left side
4z - 20 + 2 = 4z - 18
4z - 18 = 4z - 18 , which reduces to
0 = 0 ← a true statement
This indicates the equation has an infinite number of solutions
