Solution: The value of temperature is -79.6 degree fahrenheit.
Explanation:
The temperature is given in degree celsius and we have find the temperature in degree fahrenheit. The formula to convert the degree celcius in degree fahrenheit is given below,

Where, F is temperature in degree fahrenheit and C is temperature in degree celsius.
Since it is given that the temperature is -62 degree celsius. So put
in the above formula.


Hence the value of temperature is -79.6 degree fahrenheit.
Answer:
See explanations below
Step-by-step explanation:
Given the system of equation
2x - 10 y = -30 ... 1
x - 5y = 20 ... 2
Step: From 2;
x = 20 + 5y ...3
Step 2: Substitute equation 3 into 1
2x - 10y = -30
2(5y+20) - 10y = -30
Open the bracket
10y + 40 - 10y = -30
10y - 10y + 40 = -30
0+40 = -30
40 = -30
