Simplify the expression 4x + 9y + 3(x+y)

Step-by-step explanation:

4x+9y+3x+3y

=7x+12y

Simplifying the expression 4x + 9y + 3(x+y)  will give us 7x + 12y

Step-by-step explanation:

To simplify this expression;

4x + 9y + 3(x+y)

First, we will start by opening the bracket, so the expression becomes;

4x + 9y + 3x + 3y

Then we will re-arrange the expression

4x + 3x +9y +3y

We will add the the numbers with x- coefficient together and also we will add the number with y-coefficient together.  that is;add  4x and 3x together to give us 7x, also add  9y and  3y together to give us 12y

4x + 3x +9y +3y

7x +12y

we can no longer simplify anymore, so our answer is 7x + 12y
