Answer 1

Answer:

None of those answers are right. It should be

$- \frac{23}{24}$

Step-by-step explanation:

You have to find common denominators first. Multiply -5/6 by 4/4 to get -20/24. Multiply 1/8 by 3/3 to get 3/24.

$- \frac{20}{24} = z + \frac{3}{24}$

Subtract 3/24 from both sides since it is being added.

$- \frac{20}{24} = z + \frac{3}{24} \\ - \frac{3}{24} \: \: \: \: \: \: \: \: \: \: - \frac{3}{24}$

Since there are two negatives on the left, add the fractions together and keep the negative sign.

$- \frac{23}{24} = z$

You cannot reduce this fraction.
