Why is a single equation with two variables insufficient to determine a unique solution?

• It provides too much information

• It does not provide enough information

• It only allows numerical solutions

• It is always inconsistent

What is the main purpose of having a system of equations?

• To provide enough clues to solve for each variable

• To complicate the solution process

• To demonstrate mathematical theories

• To reduce the number of possible solutions

Is the pair (4, 2) a solution to the system: 2X + Y = 10, X - Y = -7?

• Yes

• No

• Insufficient information

• Irrelevant to the equations
