Is this some jiberish or is this a different language because I can’t understand nothing you just typed
After you declare a variable, you can assign a value to a variable. Assigning a value to a variable means storing a value to a variable. To assign a value, use the equal sign: var age; ... In this one line above, we declare a variable called age when we assign the value 55.

Answer:
F
=
9
5
C
+
32
Subtract 32 from both sides:
F
−
32
=
9
5
C
Multiply both sides by 5:
5
(
F
−
32
)
=
9
C
Divide both sides by 9:
5
9
(
F
−
32
)
=
C
or
C
=
5
9
(
F
−
32
)
Explanation:
Division in Java will return the integer value and disregard the remainder. This line of code will return 4.
