Question

Which statement is true?

A: A system of equations consists of two or more linear equations that must be true at the same time.

B: A system of equations consists of exactly two equations that must be true at the same time.

C: A system of equations consists of two or more equations that must be true at the same time.

D: A system of equations consists of two or more equations with at least one linear equation such that all equations must be true at the same time.

Answer 1

There are multiple different types of systems of equations. In general, a system of equations can contain any two or more linear OR non-linear equations that satisfy each other at the same time. Therefore, a systems of equations contains at least two equations that must be true at the same time, so choice C.) is correct unless it’s asking for a specific kind of system.
