Sgeneral mathematics for preparatory year students solve the equation |x + 11 = lat - 31. example 8 3. therefore. x is 12 = 1. alternatively, the give solution the equation says that r is equidistant from - 1 and 3. t the point halfway between - 1 and 3: x = (-1 + 3)/2 = 1. alte hat either x + 1 = x - 3 or r + 1 = -(x - 3). the fi equations has no solutions: the second has the solution x = 1 example 9 what values of x satisfy the inequali solution we have s-2
