Danny solved the inequality - 8x > 56 and got x>-7. Is this correct and if not, what mistake did Danny
aniked [119]

Answer:

Danny did not reverse the symbol.

Hence, the correct answer is: x

Step-by-step explanation:

Given the inequality

- 8x > 56

We know that when we multiply both sides by -1, the 'inequality' gets reverse.

i.e.

\left(-8x\right)\left(-1\right)

8x

Divide both sides by 8

\frac{8x}{8}

x

Therefore, Danny did not reverse the symbol.

Hence, the correct answer is: x
