Hello there!
[tex]Subtract[/tex] by the [tex]number [/tex] [tex]3.2 [/tex] to your [tex]sides [/tex]
Like → [tex]-0.08w + 3.2 - 3.2 \\ \\ = 4 - 3.2[/tex]
We get this→ [tex]-0.08w = -7.2 [/tex]
Since the [tex]-0.08 [/tex] goes into both of the number we would have to [tex]divide [/tex] by the decimal [tex]-0.08 [/tex] onto your [tex]sides [/tex]
Like → [tex] \frac{-0.08w}{-0.08} = \frac{-7.2}{-0.08} [/tex]
Now the we got those [tex]few [/tex] [tex]steps [/tex] out of the way we can solve our answer!
[tex] \frac{-0.08w}{-0.08} \\ (CancelOut) \\ \\ \\ \\ \frac{-7.2}{-0.08} \\ (Keep)[/tex]
[tex] \frac{-7.2}{-0.08} = 90 \\ \\ \\ Answer: w = 90 [/tex]
Good luck on your assignment and enjoy your day!
