# Class 12 RD Sharma Solutions – Chapter 9 Continuity – Exercise 9.1 | Set 3
### Question 31. If is continuous at x = 2, find k.
Solution:
Given that,
Also, f(x) is continuous at x = 2
So, LHL = RHL = f(2) …..(i)
Now,
f(2) = k ……(ii)
Let us consider LHL,
……(iii)
Using eq(i), (ii) and (iii), we get

# How do you solve 2/5=(y-26)/(y+11)?
Apr 8, 2018
$\frac{152}{3}$
#### Explanation:
First, multiply both sides by $5 \left(y + 11\right)$ to get rid of all denominators.
$\frac{2}{\cancel{5}} \times \cancel{5} \left(y + 11\right) = \frac{y - 26}{\cancel{\left(y + 11\right)}} \times 5 \cancel{\left(y + 11\right)}$
