Question 206458
{{{70=(5/9)(f-32)}}} Start with the given equation.



{{{70*9=5(f-32)}}} Multiply both sides by 9.



{{{630=5(f-32)}}} Multiply



{{{630=5f-160}}} Distribute.



{{{0=5f-160-630}}} Subtract {{{630}}} from both sides.



{{{-5f=-160-630}}} Subtract {{{5f}}} from both sides.



{{{-5f=-790}}} Combine like terms on the right side.



{{{f=(-790)/(-5)}}} Divide both sides by {{{-5}}} to isolate {{{f}}}.



{{{f=158}}} Reduce.

Answer:


So the solution is {{{f=158}}} 



Note: this means that 158 degrees Fahrenheit = 70 degrees Celsius
