#### Question 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*
+ 7 (b) (*t* − 7) > 5

(c) (d) (7 × 3) − 19 = 8

(e) 5 × 4 − 8 =
2*x* (f) *x* − 2 = 0

(g) 2*m* < 30 (h) 2*n* + 1 = 11

(i) 7 = (11 × 5) − (12
× 4) (j) 7 = (11 ×
2) + *p*

(k) 20 = 5*y* (l)

(m) *z *+ 12 > 24 (n) 20 − (10 − 5) = 3 ×
5

(o) 7 − *x* = 5

#### Answer:

(a) An
equation with variable *x*

(b) An inequality

(c) No, it is a numerical equation.

(d) No, it is a numerical equation.

(e) An e...
