It is known that the difference between the solution of the equation 2x + 3 = x + K and the solution of the equation x-3 = 5K is 6, and K =?

2X+3=X+K
∴x=k-3
X-3=5K
x=3+5k
The difference between the two solutions is 6
∴k-3-(3+5k)=6
-4k=12
k=-3

3. Please refer to the following example to solve the equation 2x-lx-1l-1 = 0. Example: solve the equation 2x-lxl-2 = 0 (1) when x is greater than or equal to 0, The original equation can be reduced to 2x-x-2 = 0, and the solution is x = 2 (2) When x < 0, the original equation can be reduced to 2x + X-2 = 0, and the solution is x = 2 / 3 Because x < 0, so x = 2 / 3 does not meet the conditions, rounding off, so the solution of the original equation is x = 2
