Answer:
x=5
Step-by-step explanation:
(5x+2)/3 = 9
Multiply each side by 3
(5x+2)/3 *3 = 9*3
5x+2 = 27
Subtract 2 from each side
5x+2-2 = 27-2
5x = 25
Divide by 5
5x/5 = 25/5
x =
P-x=n
X being the variable.
4y = -23 + 39
4y = 16
y = 4
Sub y = 4 into equation 2
7x + 6(4) = -39
7x + 24 = -39
7x = -39-24
7x = -63
x = -9
x = -9
y = 4
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
