= -4 ≥ 10 − 7x         [ changed 4 to -4 on the request of questioner ]
Subtract 10 from both sides, 
= -4 - 10 
≥ -7x + 10 - 10
= -14 ≥ -7x

Divide both sides from -7, 
= -14/-7 ≤ -7x/-7    [ sign changed as we use "-" here ]
= x ≥ 2

In short, Your Answer would be x ≥ 2 which is Option C

Hope this helps!
