7(3-x)+1 .. first you're going to distribute
21-7x+1 .. then combine like terms
22-7x .. subtract 22 from both sides to get the variable X alone.
-7x=-22
x=3.14

27 minutes at least not really sure but I’m Almost sure!!
The variable a could be

Hope I could help :)
If and only if it is a proportional relationship, the problem can be solved by creating a proportion of B1/T1=B2/T2. This can also be expressed as 4.5/3.5=5.4/x given the values. You must cross multiply, so 4.5x=3.5(5.4). This simplifies to x=4.2. So, the tail length would be 4.2 feet.
Hope this helps.
