Question

8x+4x+y+3y

Answer 1

Add the numbers that have the same variables.

Answer 2

For example something like:
\[\huge 5x + 3y + 2x + 5y\]
You add the x's and y's you get.
\[\huge 7x + 8y\]

Answer 3

You have:\[\Huge 8x + 4x + y + 3y \]
Can you simplify this? (use my example for guidance, if you have trouble with it)

Answer 4

I should add:
\[\huge y = 1y\]
so think of it as:
\[\Huge 8x + 4x + 1y + 3y\]
add the terms with the same variable.
