Solving Systems of Equations Algebraically

Find the stone in the cavern beneath the mountain. Which of the following systems of equations will yield the same solution as:

2x + 4y = -9

x - y = 3

Sneak past the Sleeping Giant. Which method could be used to eliminate one of the variables in the system below?

Equation A: 5x + 9y = 12

Equation B: 4x - 3y = 8

Beware the hunters of the sky! Solve the system using the elimination method

2x + 3y = 24

5x - 3y = -3

Defeat the Ice Mage who wants the stone for himself. Solve the system by elimination

4x + 9y = -14

2x - 3y = 8

I can solve a system of equations using elimination
