SOLUTION: I had to solve this two-step equation: 2n - 5 = 7
Here's my work:
2n - 5 = 7
2n - 5 - 5 = 7 - 5
2n = 2
2n ÷ 2 = 2 ÷ 2
n = 1
But on the answer sheet it says my answer is su

2n - 5 = 7
2n - 5 - 5 = 7 - 5
2n = 2
2n ÷ 2 = 2 ÷ 2
n = 1
But on the answer sheet it says my answer is supposed to be -10! Can anyone tell me what I'm doing wrong? Answer by Alan3354(69443) (Show Source):
You can put this solution on YOUR website! I had to solve this two-step equation: 2n - 5 = 7
Here's my work:
2n - 5 = 7
2n - 5 - 5 = 7 - 5 ************* Add 5 here, not subtract
2n = 2
2n ÷ 2 = 2 ÷ 2
n = 1
But on the answer sheet it says my answer is supposed to be -10! Can anyone tell me what I'm doing wrong?
------------------------------------
2n - 5 = 7
2n = 12
n = 6
-----------
It's not -10
