The answer is:

u > 7

In-depth explanation:

You haven't told me what the values of u are, but I'll solve the equation for u.

Add 6 on each side:


\bf{-2u-6 < -20}


\bf{-2u < -14}

Divide each side by -1 and reverse the sign:


\bf{2u > 14}

Now divide each side by 2


\bf{u > 7}

Answer:

u > 7

Explanation:

-2u -6 < -20 Add 6 to both sides

-2u - 6 + 6 < -20 + 6

-2u < -14 Divide both sides by -2. When you multiply or divide both sides by a negative number, you must flig the sign.


(-2u)/(-2) >
(-14)/(-2)

u > 7
