Answer:
a = 25 , b = 14
Step-by-step explanation:
For A
a/5 + 3 = 8
a/5 = 8 - 3
a/5 = 5
Cross multiply
a = 5 * 5
a = 25
For B
3b/7 - 1 = 5
3b/7 = 5 + 1
3b/7 = 6
Cross multiply
3b = 42
b = 42 / 3
b = 14

Given :-
- y varies directly as x, and y=14 when x=4.
To Find :-
- the value of y when x=9 .
Solution :-

- y = 7/2*9
- y = 63/2
- y = 31.5
