The set of values of x which satisfy 5x + 2 < 3x + 8 and x+2x−1 < 4 , is
Trick: By inspection, we see that all the values of x lying in (−∞,1)∪(2, 3) satisfy the equations and no other value outside the interval satisfy it.
write the set of values of x satisfying the inequations 5x+2<3x+8 and x+2x−1<4.
