Question

Jaime adds equations A and B to solve this system of equations. Why is this method

Answer 1

The elimination method is valid for the system of equation because the y term cancels.

How to solve a system of equation using elimination method?

The system of equation can be solved using elimination methods.

Therefore,

x - 2y = 3

3x + 2y = 17

Hence,

x + 3x  = 4x

-2y + 2y = 0

3 + 17 = 20

Therefore,

4x = 20

The y term cancels. Therefore, we can solve for x and later solve for y.
