Let the Number be : Z

Given : 4 less than the number is 1 more than 2 times the number

[tex]:\implies[/tex]  (Z - 4) - 1 = 2Z

[tex]:\implies[/tex]  Z - 4 - 1 = 2Z

[tex]:\implies[/tex]  Z - 5 = 2Z

[tex]:\implies[/tex]  2Z - Z = -5

[tex]:\implies[/tex]  Z = -5

Hence, the required number is -5

X-4 = 1+2X
X - 2X = 1 + 4
- X = 5
X = -5
