3x - 6y = 9 2y - x - 3 = 0
A. None B. Exactly 1 C. Exactly 2 D. Exactly 3 E. Infinitely many
Given: 3x - 6y = 9 2y - x - 3 = 0
Rewrite the bottom equation as follows: 3x - 6y = 9 -x + 2y = 3
Multiply both sides of the the bottom equation by 3 to get: 3x - 6y = 9 -3x + 6y = 9
Add the two equations to get: 0x + 0y = 18 NOTE: I know this is an odd way to express the left side of the equation, but it's the easiest way to see why there are zero solutions.
