Let's actually find the sol'n set.
<span>Line A: 2x + 2y = 8
Line B: x + y = 4
becomes
</span><span> 2x + 2y = 8
x + y = 4
------------------ Multiply the 2nd equation by -2, obtaining -2x - 2y = -8,
and then add your result to the first equation:
</span> 2x + 2y = 8
-2x - 2y = -8
------------------- Combine all 3 columns.
0 + 0 = 0
0 always = 0, so there are infinitely many solutions to this system.

something
Step-by-step explanation:
Answer:
4√3 + 13√5
Step-by-step explanation:
11√5 + 4√3 + √20. ,(20= 2√5)
