Answer:
Step-by-step explanation:x
=
y
−
8
&
−
x
−
y
=
0
Replace all occurrences of
x
with the solution found by solving the last equation for
x
. In this case, the value substituted is
y
−
8
.
x
=
y
−
8
−
(
y
−
8
)
−
y
=
0
Solve for
y
in the second equation.
Tap for more steps...
x
=
y
−
8
y
=
4
Replace all occurrences of
y
with the solution found by solving the last equation for
y
. In this case, the value substituted is
4
.
x
=
(
4
)
−
8
y
=
4
Subtract
8
from
4
.
x
=
−
4
y
=
4
The solution to the system of equations can be represented as a point.
(
−
4
,
4
)
The result can be shown in multiple forms.
Point Form:
(
−
4
,
4
)
Equation Form:
x
=
−
4
,
y
=
4
