Answer:
n=1.75
Explanation:
(7-4n)*6=0
We simplify the equation to the form, which is simple to understand
(7-4n)*6=0
Reorder the terms in parentheses
(+42-24n)=0
Remove unnecessary parentheses
+42-24n=0
We move all terms containing n to the left and all other terms to the right.
-24n=0-42
We simplify left and right side of the equation.
-24n=-42
We divide both sides of the equation by -24 to get n.
n=1.75
