How many kids does Mrs. Wood have?
y = 3x - 2
y = -x - 2
Find the solution to the system of equations:
r + s = -6
r - s = -10
(-8, 2)
Explain or Show how you would start solving this system by substution
y = x - 2
3x - y = 16
Plug in y= x - 2 into 3x - y = 16
3x - (x - 2) = 16
Set up the following equations for this example:
If Kasey orders 3 pizzas and 2 breadsticks for $25 and Marjorie orders 2 pizzas and 3 breadsticks for $20, how much does 1 pizza and 1 breadstick cost?
