Simplify the Linear Expression: 4a+(5a-2)-4a+10

$4a+(5a-2)-4a+10=$

According to the rules of the order of operations, we first eliminate the parentheses.

Remember that a positive times a positive will give a positive result, and a positive times a negative will give a negative result.

Therefore, we obtain:

$4a+5a-2-4a+10=$

Now, we arrange the exercise in a more comfortable way using the substitution property:

$4a+5a-4a+10-2=$

We solve the exercise from left to right, starting by adding the coefficients a:

$4a+5a-4a=9a-4a=5a$

Now we obtain:

$5a+10-2=5a+8$
