You can combine the same numbers with the same variables using the operation sign for each. For example, using your equation, you would combine the 3n and 4n which is 7n. So your equation would be
7n - 2

Answer:

126.

Step-by-step explanation:

Each rectangle is a step. We'll start with the top one. This is simple: 6 times 3.

$6 * 3 = 18.$

The farthest left is 5 times 3.

$5 * 3 = 15.$

The crossed one is 6 times 5.

$6 * 5 = 30.$

The one to the right of the crossed one is 3 times 5, again.

$3 * 5 = 15.$

The farthest right is 6 times 5, again.

$6 * 5 = 30.$

The bottom one is 6 times 3, again.

$6 * 3 = 18.$

Now, we add.

$18 + 18 = 36.\\15 + 15 = 30.\\30 + 30 = 60.\\36 + 30 + 60 = 126.$
