Question

two numbers are differ by 30. seven times of the smaller number is equal to its twice of the greater number.then find the number​

Answer 1

Step-by-step explanation:

x - y = 30

7y = 2x

x - 2x/7 = 30

7x-2x = 210

x = 210/5 = 42

y = 2x/7 = 12

Answer 2

a-b=30

7b=2a

so,7b-2a=60

or,5b=60

b=12 and a = 30+12=42
