You can put this solution on YOUR website!
You could with the conversion formula:
1) F+=+%289%2F5%29C%2B32 or:
2) C+=+%285%2F9%29%28F-32%29
Since you want F = C you can substitute in either equation and solve.
1) F+=+%289%2F5%29F%2B32 Solve for F. Subtract %289%2F5%29F from both sides.
-%284%2F5%29F+=+32 Now multiply both sides by -%285%2F4%29
F+=+-40
2) C+=+%285%2F9%29%28C-32%29 Multiply both sides by 9.
9C+=+5%28C-32%29
9C+=+5C-160 Subtract 5C from both sides.
4C+=+-160 Divide both sides by 4.
C+=+-40
The answer is at -40 degrees the temperature on the Farenheit scale reads the same on the Celsius scale.
