The larger number is 10 and smaller number is 6.
Step-by-step explanation:
Given,
The difference between two numbers = 4
Let,
x be the larger number.
y be the smaller number.
According to given statement;
x-y=4 Eqn 1
3y=2x-2 Eqn 2
Multiplying Eqn 1 by 3

Putting value of 3y from Eqn 2 in Eqn 3

Putting x = 10 in Eqn 2

Dividing both sides by 3

The larger number is 10 and smaller number is 6.
