Answer 1

Step-by-step explanation:

1) b) 6/ 7

2) a) 0

3) c) 6/ 10

4) 3x - 1 = 8

3x = 8 + 1

3x = 9

x = 9/3 = 3

a) 3

5) ( 4x - 1 ) / ( 2x ) = 5

( 4x - 1 ) = 2x (5)

4x - 1 = 10 x

4x - 10 x = 1

- 6x = 1

x = - 1 /6

b ) - 1/6

6 ) 7x + 1 = 4x + 7

7x - 4x = 7 -1

3x = 6

x = 6 / 3 = 2

option a) 2 is answer
