−2x+5x+6>−2
−2x+5x+6+2>0
−2x+5+2x+12x+6>0
∴17x+6>0
The above equation represents
that 17x+6>0 must be positive i.e >0
for 17x+6>0,x+6 must be greater
x+6>0
∴x>−6...(1)
Also −2x+5x+6>−2
+2x+6−2x+5<−12 [Taking reciprocal on both side changes the sign of inequality]
x+6−2+5+12<0
2×12+(−2×+5)−2x+5<0
17−2x+5<0
For the above equation to be true
−2x+5<0
x>52....(2)
After combining both the solutions
the required solution we get is
x>52
