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.
