Equation: 2x - 5 = 4x - 1
Solution: 2x - 5 = 4x - 1
Transpose: 1 + -5 = 4x - 2x
Combine Like Terms: -4 = 2x
Divide by 2: x=-2

2x - 5 = 4x - 1 transpose
4x-2x = -5+1 simplify
2x = -4 divide both side by 2
x= -2

2x - 5 = 4x -1
Now we add 5 to each side to cancel out the -5
2x -5 + 5 = 4x -1 + 5
Now solve for x
2x = 4x + 4
Anytime we need to move an integer to the other side of the equal sign, we reverse the sign.
2x - 4x = 4
-2x = 4
x = -2
