first expand the brackets
5a + 2(3a + 4) - 2a = 5a + 6a + 8 - 2a
the collect like terms
5a + 6a + 8 - 2a = 9a + 8
Unfortunately this equation dosn't simplfy becuase otherwise you could do that as well
so if wou were just wanting to simplfy the equation my work is done if you wanted to solve it and obtain a value for a you would do this
9a + 8 = 0
9a = -8
a= -8/9

It is = to:
5a+6a+8-2a which is = to:
a(5+6-2)+8 which is = to:
9a+8 stop
To test it repalce "a" with (for esample 2) in all, the result will be alwais 26.
Ciao

The best we can do is use the "Distributive Law" and collect like terms.
5a +6a +8 -2a = 11a-2a = 9a + 8. This is not an equation because there is no equals sign. This is called an "expression"

This isn't a solvable equation because there is no equal sign.
However, you can simplify this somewhat which may be what the assignment is:
You can subtract the 2 from the 5 since these are coefficients of the same thing so it becomes:
3a + 2(3a +4)

expand 2(3a+4) first
5a + 6a + 8 - 2a =
11a - 2a + 8 =
9a + 8

multiply out brackets to get a total.
So, in steps (as teacher will want working)
5a + [6a+8] -2a
3a +6a +8
9a +8
hope this helps!
