Question

What is the value of the expression-2(3x-2)+x+9 when=-3

Answer 1

Answer:

Answer is+28

Step-by-step explanation:

To solve this question,we will have to do the normal calculation first by opening the bracket then it's followed by substitution

Ok...let's start solving

Back to the question,

-2(3x-2)+x+9

Using bodmas rule

Bracket first,

-6x+4+x+9

Collect like terms

-6x+x+4+9

-5x+13

And in the question,it states that x=-3

Therefore we will have to substitute the value of x into our initial answer

-5(-3)+13

Remember that -×-=+

+15+13

=+28
