Solve using the substitution method. Show your work. If the system has no solution or an infinite number of solutions, state this.
x + 10y = 41
x + 9y = 37

x + 10y = 41 ... (1)
x + 9y = 37 ... (2)
For substitution, rewrite as
x = 4110y ...(1a)
and substitute x in (2) to get
(4110y) + 9y = 37
Simplify and solve for y.
Substitute y back in (1a) to find x.
Post for an answer check if you wish.
