Answer 1

Solution :-

`\tt:\implies (0.4x-2.8)/(4)=1.5`

`\tt:\implies 0.4x -2.8=1.5*4`

`\tt:\implies 0.4x - 2.8=6`

`\tt:\implies 0.4x=6+2.8`

`\tt:\implies 0.4x=8.8`

`\tt:\implies x=(8.8)/(0.4)`

`\tt:\implies x=\frac{\cancel{88}}{\cancel4}`

`\underline{\boxed{\red{\bf{\leadsto x=22}}}}`

`\boxed{\green{\bf \dag Hence\: value\:of\:x\:is22.}}`
