Answer:
Yep.
Step-by-step explanation:
Or you can say that x = 7.5
2x = 15
= 15/2
= 7.5
Hope this helped. :)
yes my friend thats correct
From the first example they mean that 2x will equal 15, but subbed from 5 thats 10, and THAT means that if you do 2x again but this time without the - 5, you would get 15
