Answer: 2a -5 = 7    and a = 6

Step-by-step explanation:

If 5 is less than twice a, the the expression will be  2a -5, since 2 a is the same as 2 times a, and 5 less than 2a is the same as subtracting 5 from 2a. "is" is the same as equal to, so the whole expression has to equal 7.

2a - 5 = 7   You can solve for a by adding 5 to both sides.

   +5    +5

2a = 12         Now divide both sides by 2.

a =  6.
