Question

If sum of two numbers is 30 and 2 times one number is 3 times the other then find the numbers.

Answer 1

Answer:

Sum of two numbers is 30. So, first equation will be, X + Y= 30. 2 times one is 3 times than the other. So, 2X=3Y.

Answer 2

Answer:

The Numbers are 12 and 18.

Step-by-step explanation:

LET the numbers be x and y

$given \\ \\ x + y = 30 \\ \\ 2x = 3y \\ \\ = > x = \frac{3}{2} y \\ \\ sub \: above \\ \\ \frac{3}{2} y + y = 30 \\ \\ \frac{5}{2} y = 30 \\ \\ y = \frac{2}{5} \times 30 \\ \\ y = 12 \\ \\ = > x = 30 - 12 = 18$
