Select all the equations that are true. 24 x − 8 = 8 ( 3 x − 1 ) 24 x − 8 = 8 ( 3 x − 1 ) 6 m − 15 = 3 ( 2 m − 5 ) 6 m − 15 = 3
galina1969 [7]

Answer:

24x - 8 = 8 ( 3 x - 1 )

6 m - 15 = 3 ( 2 m - 5 )

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

-8 x -12 y - 16 = - 4 ( 2 x + 3 y + 4 )

Step-by-step explanation:

Required

Select which of the equation is true

24x - 8 = 8 ( 3 x - 1 )

Open the bracket on the right hand side

24x - 8 = 8 * 3 x - 8 *1

24x - 8 = 24x - 8

Both sides of the equation are equal.

Hence, this equation is true

6 m - 15 = 3 ( 2 m - 5 )

Open the bracket on the right hand side

6m - 15 = 3 * 2m - 3 * 5

6m - 15 = 6m - 15

Both sides of the equation are equal.

Hence, this equation is true

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

Open the bracket on the right hand side

-7x - 1 = -1 * 7x -1 * 1

-7x - 1 = -7x -1

Both sides of the equation are equal.

Hence, this equation is true

16 a + 24 b = 8 ( 8 a + 16 b )

Open the bracket on the right hand side

16a + 24b = 8 * 8a + 8 * 16b

16a + 24b = 64a + 128b

Both sides of the equation are not equal.

Hence, this equation is false

-8 x -12 y - 16 = - 4 ( 2 x + 3 y + 4 )

Open the bracket on the right hand side

-8 x -12 y - 16 = - 4* 2 x -4 * 3 y -4 * 4

-8 x -12 y - 16 = -8x -12y -16

Both sides of the equation are equal.

Hence, this equation is true
