how about starting like this
2x+1 = x+2 +2
2x+1 = x+2 +2 or 2x1 = x+2+2
x+2= 2x 1 or x+2 = 2x3
now again.
x+2 = 2x1 or x2 = 2x1, where 2x+1>0 > x>1/2
x = 3 or x=1/3
or
x+2= 2x3 or x2 = 2x3 , where 2x3>0 >x <3/2
3x=5 or x = 1
x = 5/3 or x = 1
so x = 1 does not satisfy the condition
x=3 , 1/3 , 5/3 are possible solutions
testing each one in the original showed me that 1/3 does not work, so
x = 3, x = 5/3
