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 = r +7 (b) (1 - 7) > 5 2 4 (0) 2 = 2 (d) (7 X 3) - 19 = 8 (e) 5 x 4 - 8 = 2 x (f) x - 2 = 0 5x - (g) 2m< 30 (h) 2n + 1 = 11 (i) 7 = (11 x 5) - (12 x 4) 39 (k) 20 = 5y (1) 32 24 (0) 7- x = 5 (n) 20 - (10-5) = 3 x 5

(d) No, it's a numerical equation
(e) An equation with variable x
(f) An equation with variable x (g) An inequality equation
(h) An equation with variable n
(i) No, it's a numerical equation (j) An equation with variable p
(k) An equation with variable y
(1) An inequality equation
(m) An inequality equation (n) No, it's a numerical equation
(o) An equation with variable x
Answer:
(a) 17=x+7
17 = x + 7
It has an = sign
With variable x
:: It is an equation, with variable x
(b) (t-7) >5
t-7>5
It does not have = sign
:. It is not an equation
Step-by-step explanation:
(c)4/2 = 2
It has an = sign
But it does not have any variable
It is not an equation with variable
(d) (7 x 3)-19 = 8
(7×3) 198
But it does not have any variable
It is not an equation with variable.
(e) 5x4-8=2x
5x4-8=2x
It has an = sign with variable x
:: It is an equation, with variable x
(f) x-2=0
X-2=0
It has an sign with variable x
:: It is an equation, with variable x
(g) 2m< 30
2m < 20
It does not have = sign,
It is not an equation
(h) 2n + 1 = 11
2n + 1 = 11
It has an = sign, with variable n
.. It is an equation, with variable n
(i) 7= (11 x 5) - (12 × 4)
7= (11 x 5) (12 x 4)
It has as = sign
but it does not have any variable
:: It is not an equation with variable.
(j) 7 = (11 × 2) + p
7=(11 x 2) + p
It has an = sign,
with variable p.
:: It is an equation, with variable p.
(k) 20 = 5y
20 = 5y
It has an = sign
with variable y
:. It is an equation, with variable y.
(l) 3.q /2 <5
It does not have an = sign
:: It is not an equation.
