Question 251420: solve the system.
x+8y=5 (1)
x=4-8y (2)
I am supposed to type an ordered pair. I have done these before but they are not in the format that I am used to, and I also do not understand what the 1 and 2 that are in parentheses after the system mean. Please help!

x+8y=5 problem (1)
8y=-x+5
y=-x/8+5/8 (red line)
x=4-8y problem (2)
8y=-x+4
y=-x/8+4/8
y=-x/8+1/4 (green line)
+graph%28+200%2C+200%2C+-4%2C+4%2C+-4%2C+4%2C+-x%2F8+%2B5%2F8+%2C+-x%2F8+%2B1%2F4%29+ (graph 200x200 pixels, x from -4 to 4, y from -4 to 4, of TWO functions -x/8 +5/8 and -x/8 1/4).
Because these lines are parallel there is no unique solution to this set of equations.
y=-x/8+5/8
-(y=-x/8+1/4)
----------------
0+0=5/8-1/4 no solution for x or y.
