You haven't posted an equation.

**hamza**, Wednesday, December 5, 2012 at 8:31pmis it 8a+3......then a = 3-8=-5

**Ms. Sue**, Wednesday, December 5, 2012 at 8:40pmNo.

8a means 3 times an unknown number.

8a + 3 means 8 times an unknown number plus 3

The only way we can determine the value of a is in an equation. For instance,

8a + 3 = 83

8a = 83 - 3

8a = 80

a = 10
