1/2(n+1)=1/5(n-7)
We simplify the equation to the form, which is simple to understand
1/2(n+1)=1/5(n-7)
Simplifying:
+ 0.5*(n+1)=1/5*(n-7)
Simplifying:
+ 0.5*(n+1)=0.2*(n-7)
Reorder the terms in parentheses
+( + 0.5n + 0.5)=0.2*(n-7)
Remove unnecessary parentheses
+ 0.5n + 0.5=0.2+*(+n-7+)
Reorder the terms in parentheses
+ 0.5n + 0.5=+( + 0.2n-1.4)
Remove unnecessary parentheses
+ 0.5n + 0.5=0.2n-1.4
We move all terms containing n to the left and all other terms to the right.
+ 0.5n-0.2n=-1.4-0.5
We simplify left and right side of the equation.
+ 0.3n=-1.9
We divide both sides of the equation by 0.3 to get n.
n=-6.33333333333
