The answer
<span>1/(a+2) = 1/a + 1/2 this equation is equivalent to </span><span>1/(a+2) = 2+a / 2a, it means
</span>1x( <span>2a) = </span>(a+2) x(2+a) , 2a= (a+2)² =a²+4+4a, so we have a²+2a+4=0, and this last doesnt have any solution (there is no value of a verifying a²+2a+4=0)
so the answer is <span>A. no real values a.</span>

Answer:
10rupee notes are 11
20rupee notes are 22
Step-by-step explanation:
Let 10-rupee note be x
20-rupee note will be x + 11
The equation will be
10x + 20(x + 11) = 550
10x + 20x + 220 = 550
30x = 330
x = 330/30 = 11 = 10rupee notes
y = 11+11 = 22 = 20rupee notes
