Write the value of n that makes statement true (3+n) + 7=3 + (6+7)

Answer: n = 6

Step-by-step explanation:

First lets combine like terms

(3 + n) + 7 = 3 + (6 + 7)

10 + n = 16

Now let's subtract 10 on each side to isolate x

N = 6

Now let's check our work by inputting x just to make sure

(3 + 6) + 7 = 3 + (6 + 7)

9 + 7 = 3 + 13

16 = 16

So we are right!
