Answers

Answer:

The expression given in the question i.e 6x + 6 + 5x - 8 in the simplified form is 11x -2 .

Step-by-step explanation:

As given the expression in the question be as follow .

= 6x + 6 +5x -8

Simplify the above expression and it can be written as .

= 6x + 5x + 6 - 8

= 11x -2

Therefore the expression given in the question i.e 6x + 6 + 5x - 8 in the simplified form is 11x -2 .
11x-2; SInce you have to add 6x and 5x because they are 'like terms' meaning they share the same variable. You also add the 6 and the -8, which is basically doing 6-8, which equals -2. So, you put these two numbers together to get an expression of 11x-2.
