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 + 7
(b) (t-7) > 5
(c) 
= 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)

(k) 20 = 5y
(l) 
< 5
(m) z + 12 > 24
(n) 20 – (10-5) = 3×5
(o) 7 – x = 5
