What is the answer to the equation 5+2(x-1)=12

Answers

Answer 1

Answer: $5+2(x-1)=12 \n \n 2 ( x - 1) = 12 - 5 \ / \ subtract \ 5 \ from \ each \ side \n \n 2(x - 1) = 7 \ / \ simplify \n \n x - 1 = (7)/(2) \ / \ divide \ each \ side \ by \ 2 \n \n x = (7)/(2) + 1 \ / \ add \ 1 \ to \ each \ side \n \n x = (9)/(2) \ / \ simplify \n \n$

So, the answer to this problem is x = 9/2 or x = 4.5.

Answer 2

Answer: 5+2(x-1)= 12
So you need to get rid of parentheses, which is that you have to distribute.
5+2x-2= 12
-5 -5 (Inverse)
2x-2= 7
+2 +2 (Another inverse)
2x= 9
2 2 (Divide)

x= 4.5
----------------------
Check
5+2(4.5-1)=12
5+2(3.5)=12
5+7=12
12=12
