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

C=\frac{5}{9}(50-32)
C=\frac{5}{9}(18)
C= 10
50 degrees fahrenheit is equal to 10 degrees celsius 

B) you must solve the equation for F

C= \frac{5}{9}(F-32)
C/\frac{5}{9}=F-32
C/\frac{5}{9}+32=F
F= C/\frac{5}{9}+32

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

F=\frac{9}{5}C +32

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

F= \frac{9}{5}(50) +32
F= 90 + 32
F= 122

50 degrees celsius is equal to 122 degrees fahrenheit

hope this helped!

Solve 2(x + 1) = 2x + 5​
IceJOKER [234]

Answer:

no solution

Step-by-step explanation:

Given

2(x + 1) = 2x + 5 ← distribute parenthesis on left side

2x + 1 = 2x + 5 ( subtract 1 from both sides )

2x = 2x + 4 ( subtract 2x from both sides )

0 = 4 ← not possible

This indicates the equation has no solution
