Answer:
x = 1
y = - 1
Step-by-step explanation:
-8x - 3y = -5
-2x + 7y = -9 | × (-4)
-8x - 3y = - 5
8x - 28y = 36 +
________________
- 8x + 8x - 3y - 28y = - 5 + 36
- 31y = 31
31y = - 31
y = - 1
- 8x - 3(-1) = - 5
- 8x + 3 = - 5
- 8x = - 8
8x = 8
x = 1

Assume that

and <span>multiply the equation

by 4p. Then you obtain the equation

.
</span>
1) If k>0, then 4pk>0 and the equation doesn't have solutions, because <span>

and this is unreal.
</span>
<span>2) If k=0, then 4pk=0 and

. There is one solution x=h.
</span>
2) If k<0, then 4pk<0 and the equation
<span>

has two different solutions

and

.</span>
