Final answer:
The systems are not equivalent as the coefficients of the x² and y² terms are different.
Step-by-step explanation:
To determine which system is equivalent to 5x²+6y² = 50 and 7x² + 2y² = 10, we can compare the coefficients of the x² and y² terms. Both systems have x² and y² terms, but the coefficients are different, meaning the two systems are not equivalent.
