### Equation in One Variable

```

From: steph

14a + 3 = 11 - 2a
-    2a     =      2a
_________________
12a + 3 = 11

Is this right so far and how do you complete this equation?

No.  Actually, you needed to add 2a to both sides instead of
subtracting. You should get:

14a + 3 = 11 - 2a
+    2a     =      2a
_________________
16a + 3 = 11
- 3 =    - 3
_________________
16a     = 8

Then divide both sides of the equation by 16 to get:

a = 8/16 = 1/2.

Hope this helps.
