6x - 5 = 2x + 23 (add the five to the other side)
6x = 2x + 28 (minus the 2x)
4x = 28 (divide by 4)
x = 7

6x - 5 = 2x + 23
6x - 5 + 5 = 2x + 23 + 5
6x = 2x + 28
6x - 2x = 2x + 28 - 2x
4x = 2x - 2x + 28
4x = 28
x = 28/4
x = 7

6x - 5 = 2x + 23
6x - 2x = 23 + 5 (when a variable quantity or number go to the other site of "=" it swift its sign. "-" become "+" and "+" become "-")
4x = 28
x = 28/4
x=7
