6a+5a=-11

How do I work it out ?

a = -1

Step-by-step explanation:

6a+5a=-11

Since 6a and 5a have the same variables you can add them together, which gives you 11a

If you plug it back into the equation you have 11a=-11

Then to get a by itself you can divide 11 on both sides

After that, you should have a=-11/11, and any number divided by the same number is 1, but since there is a negative in the equation your answer would be -1
