55n=35n
How can that be?
sorry here is the whole question
a1plumbing service charges $35 Per hour Plus A $25 travel Charge for a Service call.Good Guys Plumbing repair charges $4O Per hour for a Service call with no travel charge.How long Must a service call be for the two companies to Charge the same amount?
a1 plumbing: cost = 35h + 25 , where h is the number of hours
Good guys : cost = 40h
so you want,
40h = 35h + 25
5h = 25
h = 5
at 5 hours the costs are the same
test it by subbing h = 5 into both of my equations
To solve the equation 55n = 35n, you can first simplify the equation by subtracting 35n from both sides to isolate n.
55n - 35n = 35n - 35n
20n = 0
Next, divide both sides of the equation by 20 to solve for n.
20n ÷ 20 = 0 ÷ 20
n = 0
Therefore, the solution to the equation 55n = 35n is n = 0.
