2s-13t=120
2S=13T+120
S=13T/2+120/2
S=13T/2+60(RED LINE)
-14s+91t=-840
-14S=-91T-840
S=-91T/-14-840/-14
S=13/2T+60 (GREEN LINE)
+graph%28+300%2C+200%2C+-10%2C+5%2C+-10%2C+60%2C+13x%2F2+%2B60+%2C+13x%2F2+%2B60%29+ (graph 300x200 pixels, x from -10 to 5, y from -10 to 60, of TWO functions 13x/2 +60 and 13x/2 +60).
THESE EQUATIONS ARE IDENTICAL THUS THERE ARE NO UNIQUE SOLUTION FOR X OR Y.
INTERCEPTS ARE: (-9.23,0) & (0,60)
