Answer:
x=0
y=8
Step-by-step explanation:
This is a simultaneous equation
So let's solve
y=-8x+8..(1)
y=-8x+8...(2)
Add (1) and (2)
2y=16
Make y the subject of formula by dividing both sides by 2
y=8
Substitute the value for y into (2)
8=-8x+8
Collect like terms
8-8=-8x
0=-8x
Divide both sides by-8
x=0
Therefore x is 0 and y is 8

Answer:
Price of skateboard= 
Step-by-step explanation:
Given: The price of a skateboard is 5 dollars less than 3 times the price of a pair of knee pads.
Lets assume the price of the knee pads be "k".
As given, The price of a skateboard is 5 dollars less than 3 times the price of a pair of knee pads.
∴ y-intercept is 5 and slope will be 3.
using y intercept expression to form an expression.
we know, 
∴ Price of skateboard= 3\times k-5
Price of skateboard= 
Hence, expression for price of skateboard is
