babunello [35]

Expression simplified: $x+9y+7$

Step-by-step explanation:

The expression that we have in this problem is:

$x+y\cdot 9 +3 +4$

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:

$y\cdot 9 = 9y$

So we can rewrite the expression as

$x+9y+3+4$

Now we can evaluate the sum of the similar terms: in this case, similar terms are only 3 and 4, and their sum is

$3+4=7$

Therefore, the expression can be rewritten as

$x+9y+7$
