Answer: infinitely many solutions

Step 1)

√25y² +16 =5y + 4

(√25y² + 40y + 16)² = (5y + 4)²

25y² + 40y + 16 = (5y + 4)²

25y² + 40y + 16 = (5y)² + 2 × 5y × 4 + 4²

25y² + 40y + 16 = 5² × y² + 2 × 5y × 4 + 4²

25y² + 40y + 16 = 25y² + 2 × 5y × 4 + 16

25y² + 40y + 16 = 25y² + 40y + 16

25y² + 40y + 16 = 25y² + 40y + 16

25y² + 40y + 16 − 25y² − 40y − 16 = 0

0 = 0
