Question

If 2x - 5 = 10, then 2x = 15

Answer 1

yes my friend thats correct

Explanation:

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

Answer 2

Yep.

Explanation:

Or you can say that x = 7.5

2x = 15

= 15/2

= 7.5

Hope this helped. :)
