A) you must plug in 50 for variable F and solve for C

C=
(5)/(9)(50-32)
C=
(5)/(9)(18)
C= 10
50 degrees fahrenheit is equal to 10 degrees celsius

B) you must solve the equation for F

C=
(5)/(9)(F-32)
C/
(5)/(9)=F-32
C/
(5)/(9)+32=F
F= C/
(5)/(9)+32

dividing by a fraction is the same as multiplying buy its reciprocal so it can also be written as

F=
(9)/(5)C +32

now you just plug in 50 for the variable C in the new equation

F=
(9)/(5)(50) +32
F= 90 + 32
F= 122

50 degrees celsius is equal to 122 degrees fahrenheit

hope this helped!
