Answer:

7x + 33 -I could be wrong I'm not an expert in maths jus trying to help

Explanation:

x + 13 9x-7

so first you need to times both by two because there are two of both sums

2(x+13) so you times both numbers by 2 so

= 2x+26

and do the same with 9x - 7 so

2(9x-7) = 18x - 14

and then you add them together and find the like terms.

Like terms means for example in the equation:

2x + 3x - 4 + 3

the like terms are the two numbers that are the same like 2x and 3x are the same since they are both the same term and since there is a plus sign before the 3x you add them so 5x and then you need to do -4 + 3 = 7 and so the answer is 5x + 7.

In this case its:

2x + 26 + 5x + 7. So the like terms are 2x and +5x and +26 and +7.

So 2x + 5x = 7x and 26 + 7 = 33.

So the final equation is 7x + 33

Hope this helps :D
