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
