Answer:

x= -5/2 x = -2.5 same thing just one is fraction and the other is decimal

Step-by-step explanation:

subtract 5 from both sides

-2(x-1)=7

divide both sides by -2

x-1= -7/2

add 1 to both sides

x= -5/2  x=-2.5

you can plug it x back in to check you answer

5 - 2 ( -5/2 -1) = 12

5 - 2 (-7/2) = 12

5 + 7 = 12

12 = 12 so this is correct
