Please provide an eplanation for this question. I'm confused.

\(7x=14+2x\)

\(5x=14\)

\(x=2.8\)

Q: Is x=2.8?

1.

\(-3x\ge-9\)

\(-x\ge-3\)

\(x\le3\)

Means;

x is either 3 or less than 3.

x can be 3,2.9,2.8,0,-90

x may or may not be equal to 2.8

Not Sufficient.

2.

\(2x\ge6\)

\(x\ge3\)

Means;

x can never be equal to 2.8 because it is either equal to 3 or more than 3.

Sufficient.

Ans: "B"

P.S.: By the way, if I consider both statements and both statements must provide true information. x=3
