Which of the following shows a system of equations equivalent to 2x + Ty = 14 and 4x + 5y = 10?
(1 point)
2x + Ty = 14 and 8x + 10y = 20
2x + Ty = 14 and 2x + 5y = 5
4x + 14y = 14 and 4x + 5y = 10
4x + 14y = 28 and 8x + 10y = 10

Answer: 2x + Ty = 14 and 8x + 10y = 20.

Reason: The second equation 8x + 10y = 20 is just 2·(4x + 5y = 10), and multiplying an equation by a nonzero constant gives an equivalent system (same solution set).
