At what point do these two lines cross?

Look at the system below. Is the x & y lined up?

$$3x=4y-7\$$  

$$3x+7y=11$$  

Is the System Lined up?

$$4y\ -\ 3x=12$$  

$$y+3x=0$$  

Are any of the coefficients same or opposite?

2x - 6y = 20

2x + 5y = -11

Are any of the coefficients same or opposite?

x - y = 11

2x + y = 19

Are any of the coefficients same or opposite?

4x+ 9y = 28

-4x -y = -28

9x-3y=-3

-5x+3y=-1

Would you add or subtract to eliminate the variable (Get ZERO)

10x-8y=-30

-10x+9y=25

Would you add or subtract to eliminate the variable (Get ZERO)

Macy starts with $20 in her bank account and she saves $5 each week. Robby has $100 in his bank account, and he saves $2.50 each week. After how many weeks will Macy and Robby have the same amount in their accounts and how much money will that be? Write a system of equations to solve.

Ride and Transport are two new ride sharing companies in Colorado. Ride is charging $2 for pick up fees and then $2.50 per mile. Transport is charging only $2.70 per mile. How many miles will it take for both companies to charge the same amount? Write a system of equations to solve.

How are you feeling about this topic (elimination) so far?
