Answer:

x = -3, y = 9

Step-by-step explanation:

-5x - 5y = -30

x - y = 6

x = -y + 6

10x + 3y = -3

10(-y + 6) + 3y = -3 (plug in x from the previous equation)

60 - 10y + 3y = -3

60 - 7y = -3

-7y = -63

<em>y = 9</em>

x = -y + 6

x = -(9) + 6

<em>x = -3</em>

Which of these equations has a solution of x = 2? Select three that apply. A 6(2x – 1) = 4 + 7x B 10 – 3x = –2(x + 4) C –3(7 – 2
Nesterboy [21]

Answer:

x = 2 for a, c, and f

Step-by-step explanation:

a)

6(2x - 1) = 4 + 7x

12x - 6 = 4 + 7x

5x = 10

x = 2

b)

10 - 3x = -2(x + 4)

10 - 3x = -2x - 8

18 = x

c)

-3(7 - 2x) = -1 - 4x

-21 + 6x = -1 - 4x

10x = 20

x = 2

d)

7x + 12 = 2(4x - 5)

7x + 12 = 8x - 10

22 = x

e)

-5(x + 1) = -4 - 7x

-5x - 5 = -4 - 7x

2x = 1

x = 1/2

f)

8x + 11 = 9(5 - x)

8x + 11 = 45 - 9x

17x = 45 - 11

17x = 34

x = 2

When two fractions are between 0 &amp; 1 half how do you know which fraction is greater explaina
oksian1 [2.3K]
 Example- 1/3 or 1/5, which is larger? If you divide 1 by 3 the answer is 0.33 If you divide 1 by 5 it's 0.2. Since 0.33(1/3) is larger that would be the answer.
sorry if I make this confusing.
basically divide the top by the bottom to see which is larger. Then compare the fractions.
