Mathematics
1 answer:
Flauer [41]3 years ago
5 0

Answer:

x = 6, y = -2

Step-by-step explanation:

24/4 = 6

x = 6

= (5x6)+8y=14

= 8y = 14 -30

8y = -16

y = -16/8

y = -2

Check: 5x6+8x-2= 14

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.
