Expression simplified: [tex]x+9y+7[/tex]
Step-by-step explanation:
The expression that we have in this problem is:
[tex]x+y\cdot 9 +3 +4[/tex]
The first type of operation that we have to solve in such expression are multiplication/division.
In this expression, there is only one multiplication, that is:
[tex]y\cdot 9 = 9y[/tex]
So we can rewrite the expression as
[tex]x+9y+3+4[/tex]
Now we can evaluate the sum of the similar terms: in this case, similar terms are only 3 and 4, and their sum is
[tex]3+4=7[/tex]
Therefore, the expression can be rewritten as
[tex]x+9y+7[/tex]
