Answer :
At F = -3, the equivalent temperature in Celsius is -19.44 degrees Celsius.
What is a linear equation?
Equations whose variables have a power of one are called linear equations. One example with one variable is where ax+b = 0, where a and b are real values and x is the variable.
The given relationship between Fahrenheit (F) and Celsius (C) scales is:
F = (9/5)C + 32
We are given that F = -3, so we can substitute this value into the equation and solve for C:
-3 = (9/5)C + 32
Subtracting 32 from both sides, we get:
-3 - 32 = (9/5)C
Simplifying the left side, we get:
-35 = (9/5)C
Multiplying both sides by 5/9, we get:
C = (-35) (5/9)
C = -19.44
Therefore, when F = -3, the equivalent temperature in Celsius is -19.44 degrees Celsius. Answer: -19.44.

-3 = 9C/5 + 32
9C/5 = - 32 - 3
9C/5 = - 35
9C = - 175
C = -175/9
C = - 19.44
9C/5 = - 32 - 3
9C/5 = - 35
9C = - 175
C = -175/9
C = - 19.44
