Question

(1)x - 3y - 3 = 0 ; 3x - 9y - 2 = 0

(2) 2x + y = 5 ; 3x + 2y = 8

(3) 3x - 5y = 20 ; 6x - 10y = 40

(4) x - 3y - 7 = 0 ; 3x - 3y - 15 = 0

by elimination method only please solve it please. ​

Answer 1

Step-by-step explanation:

(1) x-3y-3=0

x=3y+3

(I)3x-9y-2=0

3(3y+3)-9y-2=0

9y+9-9y-2=0

9-2

Answer 2

Answer:

-5=0

Step-by-step explanation:

x-3y-3=0 ......(i)

3x-9y-2=0 ........(ii)

Multiplying the (i) equation by 3

3x-9y-3=0

3x-9y-2=0

__+__+____

-5=0
