Question

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

Answer 1

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!
