I'm stuck on this problem. Can you help?
4x9y=1
x + 2y =4 WHat is x and y?
Two equations in two unknowns. Here is a quick way to solve them
4x  9y = 1
4x  8y = 16
(I got that my multiplying both side so the secind equation that you provided by 4)
Now add the two equations:
17y = 17
y = 1
Use that and any of the first equations to solve for x.
