Question

A binary operation is defined by a*b=ab if a*2=2-a find a​

Answer 1

Value of a is
`2/3`

Step-by-step explanation:

A binary operator is an operator that is applied to two or more operand like Subtract(-),Add(+),Multiply(x),Divide(
`/`).

To find possible values of a

replace * with 'x' multiply operator in the provided operation.

`axb=ab\\2a=2-a`

`2a + a = 2\\3a =2\\a=2/3`

So the possible value for a is
`2/3`
