x = 6
Step by step:
First, collect like terms:
1 + 2x - x = x - 5 + x
1 + x = x - 5 + x
1 + x = 2x - 5
Next, move terms:
1 + x = 2x - 5
(Move variable to the left side and change its sign)
1 + x -2x = -5
(move constant to the right side and change its sign)
x - 2x = -5 - 1
Next, collect like terms:
x - 2x = -5 - 1
-x = -5 - 1
(Calculate the difference_
-x = -6
Finally change the sign on both sides of the equation:
-x = -6
x = 6
