Question

Solve the given equation by elimination method
2x-3y=5
3x-y=2​

Answer 1

Answer:

Step-by-step explanation:

2x-3y=5---------------------take eq 1* by 3

3x+y=2-----------------------take eq 2*by2

after multiplying,

6x-9y=15

6x+2y=4

lets change the sign

-     -      -

-11y=11

y=-1

put the value of y in any equation 1 or 2

I put in equation 2

3x+y=2

3x+(-1)=2

3x-1=2

3x=3

x=1

Answer 2

Answer:

x=1/7,y=-11/7

Step-by-step explanation:

2x-3y=5

3x-y=2

2x-3y=5

(3x-y=2)3

2x-3y=5

9x-3y=6

2x-3y=5

-(9x-3y=6)

-7x=-1

x=1/7

(putting value in first equation

2*1/7-3y=5

2-21y=35

-21y=33

y=-11/7
