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

Starting with this:
[tex]3(2x + 4) = - 6[/tex]
First you would distribute the 3 into the ( )
so 2 would become 6 and 4 would become 12
[tex]6x + 12 = - 6[/tex]
next you subtract 12 from -6
[tex]6 x = - 18[/tex]
now you divide -18/6
[tex] \frac{ - 18}{6} = - 3[/tex]

then for #3.
[tex]3x - 3 = 13[/tex]
the next step would be to add 3 to 13
[tex]3x = 16[/tex]
then divide 3 from 16 to get
[tex] \frac{16}{3} = 5.333333333[/tex]
so around 5.3
