(a) How to represent the above situation in linear equations in two variables by taking the
number of children as 'x' and the number of adults as 'y?
(1) 2x + y = 60 (iii) 2x + 3y = 60
06) 3x + 2y = 60 (iv) 3x + y = 60
(b) If the number of children is 15. then find the number of adults?
) 10
(W) 15
(1) 25
liv) 20
(c) If the number of adults is 12. then find the number of children?
12
(iii) 15
c) 14
(iv) 18
(d) Find the value of h, if x = 5, y = 0 is a solution of the equation 3x + 5y = b
1) 12
(i) 15​

Answer 1

Answer:

1.2x+3y =60

2.10

3.12

4.15

Explanation:

2.children =15

= 2 (15)+3y=60

30 +3y =60

3y=60-30

3y=30

y=10

3. 2x+3y = 60

2x +3 (12)=60

2x+36 = 60

2x=60-36

2x= 24

x= 12

4.3x +5y =h

3 (5) + 5(0)= h

h= 15
