3.
The steps below show the incomplete solution to find the value of x for the equation

5x –2x –3 = –2 + 15:

Step 1: 5x –2x –3 = –2 + 15

Step 2: 5x –2x –3 = 13

Step 3: 3x –3 = 13

Which of these is most likely the next step? (4 points)


3x = 16

3x = 10

3x = 39

3x = 3

Answer 1

Starting with this:

`3(2x + 4) = - 6`
First you would distribute the 3 into the ( )
so 2 would become 6 and 4 would become 12

`6x + 12 = - 6`
next you subtract 12 from -6

`6 x = - 18`
now you divide -18/6

`( - 18)/(6) = - 3`

then for #3.

`3x - 3 = 13`
the next step would be to add 3 to 13

`3x = 16`
then divide 3 from 16 to get

`(16)/(3) = 5.333333333`
so around 5.3
