Question

Using four equations to solve a problem is called a four order system

Answer 1

True

Explanation:

a two-order uses two equations, and a three-order system uses three, so a four-order uses four. Keep going to n-order system.

Answer 2

The answer to your question would be true.

Similarly to fact that a two-order uses two equations, and a three-order system uses three, so a four-order uses four. Basically, just remember that the number of equations matches the number of the order.
