Answer:

1. (3/2)

2. (20)

3. (3)

4. (-9/5)

5. (-8/7)

6. (-2/3), (4)

Step-by-step explanation:

1. 2. 3. 4.

x 3 12 3 x 1 x + 3 3

/ = / / = / / = / / = /

4 8 x 5 9 x 2 5

8x = 12 60 = 3x x² = 9 5x + 15 = 6

÷8 ÷8 ÷3 ÷3 x = √9 -15 -15

5x = -9

x = (3/2) x = 20 x = 3 ÷5 ÷5

x = (-9/5)

5. 6.

4 - x 3 1 x - 3

/ = / / = /

12 7 2x + 1 9

28 - 7x = 36 9 = 2x^2 - 5x - 3

-28 -28 + 3 + 3

12 = 2x^2 - 5x

-7x = 8 -12 -12

÷-7 ÷-7

2x^2 - 5x - 12 = 0

x = (-8/7)

-b +-√b^2 - 4ac

/ = -(-5)√-5^2 - 4 (2)(-12)

2a /

2(2)

= 5-+√121 5 - 11 -6

/ = / = / = (-2/3)

-4 4 4

= 5 + 11 16

/ = / = (4)

4 4

I hope this helps!
