Question

True or False: (1/2)(2n + 2) + -2 = n

Answer 1

Add 2 to both sides. What do you get?

Answer 2

Then multiply both sides by 2.

Answer 3

this question confuses me so much

Answer 4

We're going to solve this as an equation.
To get rid of the -2 on the left side, add 2 to both sides.

Answer 5

(1/2)(2n + 2) + -2 = n
+2 + 2
----------------------------
(1/2)(2n + 2 = n + 2

Answer 6

we have :
(1/2)(2n + 2) + -2 = 1/2 * 2n + 1/2 * (-2)= n+1-2=n-1
Got it ?:)

Answer 7

thanks you! so its false then?

Answer 8

Since the left side is being multipled by 1/2, which is the same as dividing by 2, we're going to multiply both sides by 2:

2n + 2 = 2n + 4

Subtract 2n from both sides:

2 = 4 which is a false statement, so it's false.

Answer 9

and this is true right? True or False: (-5 + n) + (5 + -n) = 0 because (-5 + 5) + (n + -n)= 0 correct?

Answer 10

Yes, this is true. You are correct.
