Answer:
x = 3
y= 12
Step-by-step explanation:
2x + 2y = 30
y - 4x = 0 /*2
2x + 2y = 30
2y - 8x = 0
-----------------
10x = 30
x = 3
y= 12
Answer:
the solution is:
Step-by-step explanation:
x2 - 12x + 30 = 23!!

Answer:
The Nikes cost $125.
The Adidas cost $100
Step-by-step explanation:
Let :
- a = # of adidas shoes
- n = # of nike shoes

Solve the bottom equation for a:
Now substitute this for a in the top equation:
- 3a + 4n = 800
- 3(350 - 2n) + 4n = 800
- 1050 - 6n + 4n = 800
- 1050 - 2n = 800
- -2n = -250
- n = 125
The Nikes costs $125.
We can also solve for the Adidas:
Use the previous equation we made:
- a = 350 - 2n
- a = 350 - 2(125)
- a = 350 - 250
- a = 100
The Adidas costs $100
