For which equation is x = 5 a solution? 1. 2 + x = 3

2. 3x = 15

3. 2/x = 10

4. x − 7 = 12

2

Step-by-step explanation:

3x=15

divide both sides by 3

x=5

2. 3x = 15

Step-by-step explanation:

3x=15

divide the 3 out on both sides

so 3/3 and 15/3

and you are left with

x=5

1.) x=1

3.)x=1/5

4/)x=19

So number two is the correct answer.

i think it is x = 1.2

idk lol
