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)

Here is the answer that is on meritnation
Answer:(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)
