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
