Question

solve the following by elemination method x/2 +2y /3=-1 x-y/3=3​

Answer 1

Answer:

$x = \frac{14}{5} \: and \: y = - \frac { 3}{5}$

Step-by-step explanation:

The explanation is in the above attachment.

Answer 2

Answer:

x = 2

y = -3

Step-by-step explanation:

x/2 + 2y/3 = -1 -1

x - y/3 = 3 -2

multiply equation 2 by 2 and then add equation 1 and 2...

x/2 + 2y/3 = -1

(+) 2x - 2y/3 = 6

____________

5x/2 + 0 = 5

x = 5 *2 /5

x = 2

substitute value of x in equation 2...

2 - y/3 = 3

2 - 3 = y/3

-1 * 3 = y

y = -3
