Question

solve the equation (using method of your choice) 3x-5y=5 ;6x-10y=10​

Answer 1

Answer:

Given

the

system

of

equation

3x+5y=20..(i)

6x−10y=−4..(ii)

Multiply by 2 in equation (i)

6x+10y=40..(iii)

6x−10y=−4..(ii)

by additional

⇒ 12x=36

⇒ x=

12

36

⇒ x=3..(iv)

Putting the value of x from (iv) in equation (i)

⇒ 3×3+5y=20

⇒ 9+5y=20

⇒ 5y=20−9

⇒ 5y=11

⇒ y=

5

11

x=3,y=
