Question

3.By taking x=y=a and z= = verify that:- x = (y – z) = (x + y) - (x = z)​

Answer 1

Answer:

Using, (x + y) × z = x × z + y × z

⇒ [4/5 + (-2/3)] × (-4) = 4/5 × (-4) + (-2/3) × (-4)

⇒ ( (4 × 3)/(5 × 3) – (2 × 5)/(3 × 5) ) × (-4) = (-16/5) + 8/3

⇒ (12 – 10)/15 × (-4) = (- 48 + 40)/15

= (-8/15) = (-8/15)
