Which of these values of x satisfies the inequality -7x+6≤ -8?

Mar 13, 2018

Solution: $x \ge 2 \mathmr{and} \left[2 , \infty\right)$

Explanation:

$- 7 x + 6 \le - 8 \mathmr{and} - 7 x \le - 8 - 6 \mathmr{and} - 7 x \le - 14$

Multiplying by $- 1$ on both sides we get,

$7 x \ge 14 \mathmr{and} x \ge 2$

Solution: $x \ge 2 \mathmr{and} \left[2 , \infty\right)$ [Ans]
