Answer:
Step-by-step explanation:
In this particular case we have the following system of equations:
y
=
−
3
x
+
4
[
E
q
.
1
]
x
+
4
y
=
−
6
[
E
q
.
2
]
Substituting
[
E
q
.
1
]
in
[
E
q
.
2
]
:
x
+
4
(
−
3
x
+
4
)
=

6
Applying the distributive property on the left side:
x
−
12
x
+
16
=

6
Simplifying
:
−

x
=
−
22
Solving for
y
:
x
=
−
22
−
11
=
2
Substituting
x
=

in
[
E
