Answer 1

i need help on this onee

Answer 2

Rearrange the second equation to yield
y=2x - 1

Substitute this into the first equation to yield

2(2x-1)=8-x
you can then rearrange this to find an expression for x;

x=2

Finally, substitute this into the second equation to find y;

y=3

Answer 3

Thanks so much alde.e

Answer 4

2y=8-x y-2x=-1
x=0 x=8 x=0 x1/2
y=4 y=0 y=-1 y=0
