Answer
The system is inconsistent.
No solutions.
Work Step by Step
We generated values for $t$ until we observed that
for a change in $t$ of +1, $R$ changes in both cases by +$0.8$.
So, both have slopes $m=0.8/1=0.8.$
In the row in which $x=0$, the y values are diferent, so the y-intercepts are different.
These are parallel lines that do not intersect.
The system is inconsistent.
No solutions.
