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) `4/2 = 2` (d) `(7 xx 3) -19 = 8` (e) `5 xx 4 - 8 = 2 x` (f) `x - = 0 ` (g) `2 m < 30` (h) `2 n + 1 = 11 ` (i) `7 = (11 xx 5) - (12 xx 4)` (j) `7 = (11 xx 2 ) + p` (k) `20 = 5 y ` (l) `(3 q)/ 2 < 5` (m) `z + 12 > 24 ` (n) `20 = (10 - 5) = 3 xx 5 ` (o) `7 - x = 5`
