Answer:
The answer to your question is: x = 7; y = 6
Step-by-step explanation:
2x+y=20 ( 1 ) Multiply by 5
6x−5y=12 ( 2 )
5 (2x+y=20) = 10x + 5y = 100
10x + 5y = 100
6x − 5y = 12 Eliminate y
16 x = 112
x = 112 / 16
x = 7
2(7) + y = 20 Substitution
14 + y = 20
y = 20 - 14
y = 6
C= 5/9 * (F -32)
Move 5/9 to the left which makes it 9/5
9/5 * C = (F -32)
Move the -32 to the left
9/5 * C +32 = F or to make it read left to right
Fahrenheit = 9/5 * Celsius + 32
