The parts of the given question are solved below:

Here,

We have to frame three equations starting with x = 2

We have,

x = 2

Now,

Multiplying both sides by 5, we get:

5x = 10 (i)

Now,

Subtracting 3 from both sides, we get:

5x – 3 = 10 – 3

5x – 3 = 7 (ii)

Now,

Dividing both sides by 4, we get:

(iii)

Hence,

(i), (ii) and (iii) are the required equations.
