Solution :-

[tex]\tt:\implies \dfrac{0.4x-2.8}{4}=1.5[/tex]

[tex]\tt:\implies 0.4x -2.8=1.5\times4[/tex]

[tex]\tt:\implies 0.4x - 2.8=6 [/tex]

[tex]\tt:\implies 0.4x=6+2.8 [/tex]

[tex]\tt:\implies 0.4x=8.8 [/tex]

[tex]\tt:\implies x=\dfrac{8.8}{0.4} [/tex]

[tex]\tt:\implies x=\dfrac{\cancel{88}}{\cancel4} [/tex]

[tex]\underline{\boxed{\red{\bf{\leadsto x=22}}}}[/tex]

[tex]\boxed{\green{\bf \dag Hence\: value\:of\:x\:is22.}}[/tex]
