The value of "n" will be "3.8".
Given expression is:
- [tex]0.3(n-5)=0.4-0.2n[/tex]
By solving the brackets, we get
→ [tex]0.3n - 1.5=0.4-0.2n[/tex]
By adding "0.2n" both sides, we get
→ [tex]0.3n - 1.5+0.2 n=0.4-0.2n+0.2 n[/tex]
→ [tex]0.5 n-1.5= 0.4[/tex]
By adding "1.5" both sides, we get
→ [tex]0.5 n-1.5+1.5= 0.4+1.5[/tex]
→ [tex]0.5n = 1.9[/tex]
[tex]n = \frac{1.9}{0.5}[/tex]
[tex]= 3.8[/tex]
Thus the above answer is below.
