Travolta is playing a card game. He has -2, 6, and -9. To win the game, he can only pull one more card, and all his numbers need to add up to zero. What must be the number of his final card to win the game? Calculate the number of the final card, and write an equation representing the total from his hand. Sadly, he lost the game because he pulled a 7. What was his final score? 4: Correct card number, equation, and final score 3: Correctly complete two of the requirements 2: Correctly complete one of the requirements 1: Unsuccessfully complete any of the requirements

Ok here we go ..there are plenty of ways to solve such math problems but we will go for the smartest and easiest ..5x+2y=7  -2x+6y=9we rearrange them into the following ..by multiplying the 1st equation by 2 it becomes 10x + 4y = 14we rearrange it and so it becomes 10x = 14 - 4yas for the second equation we multiply it by 5 and rearrange it so it becomes as to the following ..-10x + 30y = 45rearranging so 10x = 30y -45now 10x equals both 14 - 4y and 30y -45so   14 - 4y = 30y -4531 = 26yy= 31/26 = 1.19 or around 1.2so by now we can calculate x easily as  -2x+6y=9so 2x = 6y -9 = 6 * 31/26 - 9 = -1.84  then x = - 0.92 or around -0.9best luck!
