Answer:
The solution is the point
(
5
,
6
)
.
Explanation:
Equation 1:
4
x
+
y
=
26
Equation 2:
5
x
−
2
y
=
13
We can use addition/elimination and substitution to solve this system.
Multiply Equation 1 by
2
.
2
(
4
x
+
y
)
=
26
×
2
Simplify.
8
x
+
2
y
=
52
Add Equation 1 and 2.
8
x
+
2
y
=
52

2
y
=
13

.
=
65
Divide both sides by
13
.
x
=
65
13
x
=
5
Substitute
5
for
x
in Equation 2 and solve for
y
.

−
2
y
=
13
25
−
2
y
=
13
Subtract
25
from both sides.
−
2
y
=
13
−
25
−
2
y
=
−
12
Divide both sides by
−
2
.
y
=
−
12
−
2
←
Two negatives make a positive.
y
=
6
The solution is the point
(
5
,
6
)
.
