Question

Solve by cross multiplication method x/2 + 2y/3 = -1 and x-y/3 = 3.

Answer 1

Answer:

Ans.  1 ) −4/3y−2

Ans.  2) 1/3y+3

Answer 2

Answer:

x/2 + 2y/3 = -1

Step-by-step explanation:

LCM of 2 and 3 = 6

Therefore, x/2 × 3/3 = 3x/6 and 2y/3 × 2/2 = 4y/6

3x/6 + 4y/6 = 1/1

(3x + 4y)/ 6 = 1/1

(3x + 4y)/ 1 = 6/1

3x + 4y = 6

_________________________________

(x - y)/3 = 3

(x - y)/3 = 3/1

(x - y)/1 = 3 × 3

x - y = 9
