Question

For both questions can someone please fill in the missing numbers in the tables thannks!

Answer 1

Step-by-step explanation:

a.
if x=-1 then,
y=2*(-1)-1
y=-2-1
y=-3

if y=-1 then,
-1=2x-1
-2x=-1+1
-2x=0
x=0

if x=1 then,
y=2*1-1
y=2-1
y=1

if y=3 then,
3=2x-1
-2x=-1-3
-2x=-4
-2/-2x=-4/-2
x=2

b.
if x=0 then,
0+y=-2
y=-2

if x=1 then,
y+1=-2
y=-1-1
y=-3

if x=2 then,
y+2=-2
y=-2-2
y=-4

if x=3 then,
y+3=-2
y=-2-3
y=-5
