Answer 1

Answer: x=114

Step-by-step explanation:

To solve for x, we want to isolate x.

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

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

$0.2x=22.8$                      [divide both sides by 0.2]

$x=114$

Now, we know that x=114.
