Either the first or third are positive
Answer:
If a graphical plot is made with sufficient resolution linear equations may be solved by observing the solution point(s) on the graph coordinates.
In this case, the lines
y
=
x
+
2 and y
=
x
2
−
2
should be plotted.
They will intersect at the point (-8, -6) when the resolution of the graph is properly adjusted.

Step-by-step explanation:
<u>Define:</u>
Let the number of messages Dale sent= x
The number of messages Yolanda sent = x + 6
The number of messages Tony sent = 3(x + 6)
<u>Equation:</u>
x + (x + 6) + 3(x + 6) = 114
x = 19
<u>Answer:</u>
Dale = 19
Yolanda = 25
Tony = 75
