In order to solve the system of equations below, Harvey multiplies each equation by a constant to eliminate the x terms.

7 x + 3 y = 5. 2 x + 5 y = negative 11.

What are the resulting equations?
14 x + 6 y = 10. Negative 14 x minus 35 y = 77.
14 x + 6 y = 10. Negative 14 x + 35 y = 77.
14 x + 6 y = 10. Negative 14 x minus 35 y = negative 77.
Negative 14 x minus 6 y = 10. 14 x + 35 y = negative 77.
