Answer: x=114

Step-by-step explanation:

To solve for x, we want to isolate x.

[tex]\frac{0.2x-1.8}{5}=4.2[/tex]                   [multiply both sides by 5]

[tex]0.2x-1.8=21[/tex]                [add both sides by 1.8]

[tex]0.2x=22.8[/tex]                      [divide both sides by 0.2]

[tex]x=114[/tex]

Now, we know that x=114.
