Question

4 times itself and plus 1 equals this number. What is the number?

Answer 1

Let the no be x

`\\ \sf\longmapsto 4x+1=x`

`\\ \sf\longmapsto 4x-x=1`

`\\ \sf\longmapsto 3x=1`

`\\ \sf\longmapsto x=1/3`

Answer 2

The number = -0.3

Explanation:

Let the number equal x:

4x+1=x

4x=x-1

3x=-1

x=-1/3 or x=-0.3

Proof:

4(-0.3)=-1.3

-1.3+1=-0.3

The number = -0.3
