# Q.1 State which of the following are equations (with a variable). Give reason for your answer. Identify the variable from the equations with a variable. (a) 17 = x + 17 (b) (t – 7) > 5 (c) $$\frac{4}{2}$$ = 2 (d) (7 × 3) – 19 = 8 (e) 5 × 4 – 8 = 2x (f) x – 2 = 0 (g) 2m < 30 (h) 2n + 1 = 11 (i) 7 = (11 × 5) – (12 × 4) (j) 7 = (11 × 2) + p (k) 20 = 5y (l) $$\frac{2q}{2}$$< 5 (m) z + 12 > 24 (n) 20 – (10 – 5) = 3 × 5 (o) 7 – x = 5
