21 + 7 = BD Substitution
28 = BD Add Like Terms
A system of equations has an infinite number of solutions when after solving the system, you end up with a true statement.
For example, let’s say you solve a system of equations and your result is 5=5. 5=5 is a true statement, but it doesn’t tell us anything about the x or y value solutions to the system. So because we’re only left with 5=5, there are infinite solutions to the system.
The answer is c because it is a perfect square.hope this helps ask me questions and i will be glad to answer it.
