Step-by-step explanation:
formula is:
(°F − 32) × 5/9 = °C
39°F = (39-32) x 5/9 = 3.9°C
5 F to C = -15 °C
3 x 25 = 75
4 x 12 = 48
75 - 10 = 65
65 + 48 = 113
Answer: 113 markers and crayons or 65 crayons and 48 markers
He can conclude that the system of equations has no solution since one equation in it always results with false equivalency.
Hope this helps.
