If the 2

If the temperature is 86 degrees in Fahrenheit, what is the same temperature in Celsius?

Result

t2 =  30 °C

Solution:

t1=86 ∘F  t2=59⋅ (t1−32)=59⋅ (86−32)=30=30∘Ct_{1}=86 \ ^\circ \text{F} \ \\ \ \\ t_{2}=\dfrac{ 5 }{ 9 } \cdot \ (t_{1} - 32)=\dfrac{ 5 }{ 9 } \cdot \ (86 - 32)=30=30 ^\circ \text{C}
