Simultaneous equations and inequalitiesExam-style questions

Two conditions at once, and conditions that pick out a range. What solving simultaneously means on a graph; a line meeting a curve, with the answers given as pairs; counting the meeting points with the discriminant; linear inequalities, and why dividing by a negative turns the sign round; quadratic inequalities from the critical values and a sketch; and the outside region, set notation and combining two conditions.
