Question 4:

(a) Construct 3 equations starting withx= 2

(b) Construct 3 equations starting withx= 2

The question here instructs you to create 3 equationsstarting with x =2 and 3 more equationsstarting with x=-2 but the answer to it on the meritnation website is constructing 3 equation with theansweras x=2 and 3 more equations with the answer as x=-2.

Here is the answer that is on meritnation

(a) x= 2

Multiplying both sides by 5,

5x= 10 (i)

Subtracting 3 from both sides,

5x 3 = 10 3

5x 3 = 7 (ii)

Dividing both sides by 2,

(b) x= 2

Subtracting 2 from both sides,

x 2 = 2 2

x 2 = 4 (i)

Again,x= 2

Multiplying by 6,

6 ×x= 2 × 6

6x= 12

Subtracting 12 from both sides,

6x 12 = 12 12

6x 12 = 24 (ii)

Adding 24 to both sides,

6x 12 + 24 = 24 + 24

6x+ 12 = 0 (iii)
