I don't know how to answer this question.
laiz [17]

Answer:

- 39/8y

Step-by-step explanation:

First you need to find a common denominator:

There is already a y in both denominators, so you don't have to worry about that. Since only one denominator has an 8, the other needs to have an 8, so you need to multiply the first fraction by 8 → - 4/y * 8 = - 32/8y

From here you can subtract the numerators:

- 32/8y +(- 7/8y) = - 39/8y

Because you are adding a negative to a negative, it makes the number mroe negative


I hope this helps!

Which of the following ordered pairs are solutions to the system of equations below?
Genrish500 [490]

Answer:

x = 43/12

y = - 35/6

Step-by-step explanation:

4x + 4y = -9

y = 2x - 13

4x + 4(2x - 13) = - 9

4x + 8x - 52 = - 9

12x = 52 - 9

12x = 43

x = 43/12

y = 2×43/12 - 13

y = 86/12 - ¹²⁾13

y = (86 - 156)/12

y = - 70/12

y = - 35/6
