Answer 1

Answer 2

22x

Answer 3

You can always add it if it has the same variable. Because 7x and 15 x do (as they both have an x with an exponent of 1), then you can just add them together to get 22x.

Answer 4

thanks guys!

Answer 5

if you want an intermediate step,
you can factor out the x

\[7x + 15x =(7+15)x\]
