Question

`4x/(1-x) when x= -3\\`

Answer 1

Hello!

Answer:

`\Large \boxed{\sf -3}`

Explanation:

We have the expression:

`\sf (4x)/(1-x)`

We want the result when x = -3.

Go replace x by -3:

`\sf (4(-3))/(1-(-3))`

Simplify the expression:

`\sf (-12)/(4) = -3`

Answer 2

Given to us that:–

• 
  `\sf{(4x)/((1-x))}`
• 
  `\sf{x = -3}`

To find:–

• Value of the expression

By substituting the value of x ,

➱
`\sf{(4(-3))/(1-(-3))}`

➱
`\sf{(-12)/(1+3)}`

➱
`\sf{(-12)/(4)}`

➱
`\sf{-3}`

Henceforth, Value of the expression: -3
