Question

if (a+b )is twice( a-b),then what is the value of a​

Answer 1

a=3b

Step-by-step explanation:

a+b=2(a-b)

a+b=2a-2b

a-2a+b+2b

-a+3b=0

a=3b

Answer 2

The value of a is thrice of b ( a = 3b)

According to the question, it is given that,

(a+b) is twice that of (a-b).

So we represent the above expression as,

(a+b) = 2(a-b)

⇒ (a+b) = 2a - 2b

⇒ 2a-a = b+2b

⇒ a = 3b

Thus, the value of a is thrice of that of the value of b.
