Question

(2) The sum of two numbers is 25. Ir thrice the smaller number is subtracted
from twice the larger number, the subtraction is also 25. Find the
numbers.​

Answer 1

Answer:

a+b=25

b=25-a------1

3a-2b=25–-----2

By substituting value of b in 2

3a-2(25-a)=25

3a-50+2a=25

5a=75

a=15

value of b from 1=10

Answer 2

Answer:

5 and 20

Step-by-step explanation:

$\left \{ {{x+y=25} \atop {2y-3x=25}} \right.$

multiply the above equation by -2

$\left \{ {{-2x-2y=-50} \atop {2y-3x=25}} \right.$

add each term

$-5x=-25$

calculate x and then y

$x=5\\y=20$
