Here are the steps to calculating the given equation:
Distribute 2 to x and 6: 2x-12+14=38 Group like terms: 2x+(-12+14)=38 Combine like terms: 2x+2=38 Subtract number on 'x' side: 2x+2-2=38-2 Simplify: 2x=36 Divide: 2x/2=36/2 Simplify: x=18 Label with correct terms: I cannot do this because you did not provide sufficient information, I would need to know what the difference between the two, or if 'x' stood for one particular temperature. Hope that helped enough with what you provided.
