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