Solve by substitution method.
6x+9y=12
5x+y=27
What is the solution of the system? Type an ordered pair... Please help
Thanks!

to solve with substitution is simple. Set the second problem equal to y. then insert this value in for y in the first equation.
6x+9y=(12)
y=27+5x
6x+9(27+5x)=(12)
Take is from here.
