What is the solution to the system of equations?2x-y=7y=2x+3​

Engineering
1 answer:
AleksAgata [21]3 years ago
6 0

Answer:

No solution.

Explanation:

Solve with substitution or elimination.

If you use substitution, plug the expression for y in the second equation into the first equation.

2x − (2x + 3) = 7

2x − 2x − 3 = 7

-3 = 7

No solution.

If you use elimination, add the equations together to eliminate y.

2x − y + y = 7 + 2x + 3

2x = 10 + 2x

0 = 10

No solution.

There is no solution.

Air is compressed by a 30-kW compressor from P1 to P2. The air temperature is maintained constant at 25°C during this process as
adell [148]

Answer:

-0.1006Kw/K

Explanation:

The rate of entropy change in the air can be reduced from the heat transfer and the air temperature. Hence,

ΔS = Q/T

Where T is the constant absolute temperature of the system and Q is the heat transfer for the internally reversible process.

S(air) = - Q/T(air) .......1

Where S.air =

Q = 30-kW

T.air = 298k

Substitute the values into equation 1

S(air) = - 30/298

= -0.1006Kw/K
