Annie was going to use the elimination method. She was ready to add the same value to both sides of the equation to eliminate the x-terms when she noticed a problem: Both x-terms are positive! 2x+7y=13
2x+3y=5

Rather than adding the equations together, how else could you eliminate the x-term? Once you have figured out a method, solve the system and check your solution.

The value of x in this system of equations is 1. 3x + y = 9 y = –4x + 10 substitute the value of y in the first equation: combine like terms: apply the subtraction property of equality: apply the division property of equality: 3x + (–4x + 10) = 9 –x + 10 = 9 –x = –1 x = 1 what is the value of y?

Which shows how to solve the equation 3/4x=6 for x in one step?

The host of a game show is holding a bag with chips to see what prizes the contestants will play for. five (5) of the chips say “new car” ten (10) of the chips say “new tv” three (3) of the chips say “trip to france” contestant named “patty” reaches into the bag. a. what is the probability of choosing a tv chip? b. what is the probability of choosing a car chip next without replacing the 1st chip? c. are these dependent or independent events?
