$x \geq - 0.6$ $x\geq-0.6$

Explanation:

Replace the inequality sign with an equal sign and continue simplifying as you would with a usual linear equation, then replace the equal sign with the same sign in the question.

$5 x + 7 = 4$ $5x+7=4$

$5 x = - 3$ $5x=-3$

$x = - \frac{3}{5}$ $x=-3/5$

$x = - 0.6$ $x=-0.6$

So

$x \geq - 0.6$ $x\geq-0.6$
