Yes. To do the calculation by hand you can subtract 32 from the original number, multiply that by 5, and then divide by 9.

Undefined: You cannot divide by zero
The question contains an expression but not an equation. An expression cannot be solved.

It is not possible to answer the question because it is not clear what 75 is to be divided by.
(n-4)/5 Remember p.e.m.d.a.s. The parentheses signify which part of the expression to do first. They are very important. You get a different answer without them.
The answer is 36.92. First, divide 17.95 by 2 to get 8.975, then subtract 8.975 from 45.90 to get 36.92.
You can:* Add the same expression to both sides of an equation * Subtract the same expression from both sides * Multiply the same expression (must not be zero) to both sides * Divide both sides by the same expression (must not be zero)
