A. one solution. there is one point that satisfies. if you want to check, graph both functions and find the intersect. that point, and that point only, will satisfy both equations.

thank you

anonymous · Answer

that is wrong

anonymous · Answer

they are the same equation there are infinitely many solutions

anonymous · Answer

use substitution

anonymous · Answer

use nothing
they are the same equation

lol

anonymous · Answer

x = -4y + 4 
2x + 8y = 8
-----------------
2x + 8y = 8
2(-4y + 4) = 8
-8y + 8 = 8
-8y = 0
---   ---
-8      -8

y = 0

----------------
x = -4y + 4
x = -4(0) + 4
x = 0 + 4
x = 5

----------------------------

Solution (5, 0)
1 solution
