    Lamen terms? Do you mean layman terms? Anyway, you were given the value of C so first thing to do is to substitute (-38) in place of C in the equation. 5C means 5 multiplied by C so you know that 5C = 5(-38) = -190.

    9/5C + 32. Is this (9/5C) + 32, meaning you divide 9 by 5C before adding 32, or 9/(5C + 32), meaning you add 5C to 32 and using the sum as divisor of 9?

    Assuming the first:

    F = (9/5C) + 32

    = (9/-190) + 32

    = -0.04736842105 + 32

    = 31.952631579

    Assuming the second:

    F = 9 / (5C + 32)

    = 9 / (-190 + 32)

    = 9 / -158

    = - 0.05696202532

    Oh, I see that the others interpreted it as F = (9/5)C + 32.

    In that case:

    F = (9/5)C + 32

    = ((9*-38) / 5) + 32

    = (-342 / 5) + 32

    = -68.4 + 32

    = -36.4

    Remember, all these letters in equations represent numbers so if you are given the value of the letter (example: C = -38) then all you need to do is to substitute the values in order to find the solution. Also in math, you have to copy your questions accurately or else you will not get the right answer. Math is an exact science. There is no room for guessing.

    Divide 9 by 5 then multiply the answer by -38 and finally add 32. That's how you find F.

    F = 9/5(-38) + 32

    F = -36.4.

    Just plug in -38. Multiply -38 by 9/5 and add 32. This is how one converts from Celsius to Fahrenheit.

    F = 9*-38/5 + 32 = -36.4

    F = 9/5( - 38) + 32......F = (9( - 38))/5 + 32.......F = - 68.4 + 32 = - 36.4
