Mathematics
1 answer:
fiasKO [112]3 years ago
5 0

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
