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

(50-32)
C=

(18)
C= 10
50 degrees fahrenheit is equal to
10 degrees celsius B) you must solve the equation for F
C=

(F-32)
C/

=F-32
C/

+32=F
F= C/

+32
dividing by a fraction is the same as multiplying buy its reciprocal so it can also be written as
F=
C +32
now you just plug in 50 for the variable C in the new equation
F=

(50) +32
F= 90 + 32
F= 122
50 degrees celsius is equal to
122 degrees fahrenheit
hope this helped!
Let's translate the expression step by step:
"Five less than..."
we will have to subtract five from something
"two times a number"
.
So, we have
"Five less than two times a number"
.
This "is sixty-nine", where "is" means "is equal to". So, the equation is

Answer:
f = 8
Step-by-step explanation:
9f = 8f + 8
9f - 8f
= f
So, f = 8
9(8) = 8(8) + 8
72 = 72
