Question

4(x-3) < x+3, Where x ∈ W
Please help me​

Answer 1

`\large\underline{\sf{Solution-}}`

Given:

`\rm\longmapsto 4(x-3)<x+3, x\in \mathbb{W}`

`\rm\longmapsto 4x-12<x+3`

`\rm\longmapsto 4x-12-x<x+3-x`

`\rm\longmapsto 3x-12<3`

`\rm\longmapsto 3x-12+12<3+12`

`\rm\longmapsto 3x<15`

`\rm\longmapsto (3x)/(3)<(15)/(3)`

`\rm\longmapsto x<5, x\in\mathbb{W}`

`\large\underline{\sf{Answer-}}`

Therefore:

`\rm\longmapsto x=\{0,1,2,3,4\}\ \ \`
