Question

solve by elimination method-2a+3b=5,3a-b=-9​

Answer 1

Answer:

Step-by-step explanation:

[1]    2a - 3b = 5

  [2]    -3a + b = 3

Answer 2

Answer:

Multiply 3a-b=-9 and - 2a+3b=5 by 2 and 3

2(3a-b)=-9 x 2

3(-2a+3b)= 5 x 3

6a-6b=-18

-6a+9b=15

= 3b = - 3

=b=-3/3=-1

Putting - 1 in equation 3a-b=-9

3a-(-1)=-9

3a +1=9

3a=9-1

3a=8

A=8/3

Hope it's helpful to you.

According to my point of view this is the correct answer.
