ANSWER
{c} 2
Step By Step Explanation
Here we have >
So we have
=> -------(i)
Also,
=> ----------(ii)
Now, On squaring both sides of we get =>
(x + 5) + (5 - x) + = 16
=> 10 + = 16
{By using (a+b)(a-b) = a² - b²}
=> = 16 - 10
=> =
=> = 3
Now on squaring both sides we have >
=> 25 - x² =9
=> x² = 16
=> x =
=>x =
Hence the number of solutions available for the equation are 2.
