Ex 6.1, 3 Solve 5x – 3 < 7, when x is an integer 5x – 3 < 7 5x < 7 + 3 5x < 10 x < 105 x < 2 Since x is an integer (……,-3,-2,-1,0,1,2,3….) We need to find values of x which is less than 2 i.e. x can be ……-3,-2,-1,0,1 = {……–3, –2, –1, 0, 1} (ii) x is a real number Now, x < 2 Since x is a real number which is less than 2 Thus x ∈ (– 2).
