4a - 6 = 5 + 6a
4a - 6 - 6a = 5 + 6a - 6a
-2a - 6 = 5
-2a - 6 + 6 = 5 + 6
-2a = 11
-2a / -2 = 11 / -2
a = -11 / 2 = -5.5

Its simple algebra!

All u gotta do is solve for the variable which in this case is "a".

Now here we go:

Note: Before solving, make a note that we always put like terms on one side of the equation)

So..

=> 4a - 6 = 5 + 6a
=> 4a - 6a = 5 + 6
=> -2a = 11

Now divide both sides by -2 and u get:

=> -2a/-2 = 11/-2
=> a = -11/2

And thas ur answer!

Reminder: 11/-2 or -11/2 are the same thing. You could put the minus sign anywhere as long as the signs dont cancel with each other!)

4a - 6 = 5 + 6a

Trnspose 4a

4a - 6 - 4a = 5 + 6a - 4a

Collect like terms

- 6 = 5 + 2a

Transpose 5

- 6 - 5 = 5 + 2a - 5

- 11 = 2a

Divide both sides of the equation by 2

- 11 / 2 = 2a / 2

- 11/2 = a

- 5 1/2 = a

- 5.5 = a

Isolate the variable.

4a - 6 = 5 + 6a
4a = 5+ 6 + 6a
4a = 11 + 6a
4a - 6a = 11
-2a = 11
a = - 5.5

The easiest way is to combine like terms. Subtract 4a from both sides and 5 from both sides and you get;

4a-4a-6-5 = 5-5+6a-4a or
-11=2a

Divide both sides by 2 and you have your answer:

-11/2 = a
