22.5+7 (n-3.4)=19.8n

We simplify the equation to the form, which is simple to understand
22.5+7(n-3.4)=19.8n

Reorder the terms in parentheses
22.5+(+7n-23.8)=19.8n

Remove unnecessary parentheses
+22.5+7n-23.8=+19.8n

We move all terms containing n to the left and all other terms to the right.
+7n-19.8n=-22.5+23.8

We simplify left and right side of the equation.
-12.8n=+1.3

We divide both sides of the equation by -12.8 to get n.
n=-0.1015625
