Question

2x+5y=8/3 , 3x-2y=5/6 by Cross multiplication​

Answer 1

Answer:

x=221/342 and   y=3  

Step-by-step explanation:

2x+5y-8/3=0   Here, take LCM=3

3x-2y-5/6=0   Here, take LCM=6

So the equations will be

6x+15y-8=0

18x-12y-5=0

a1= 6  ,a2= 18

b1= 15  ,b2= -12

c1= -8   ,c2= -5

x/b1c2-c1b2 - y/c1a2-a1c2 - 1/a1b2-b1a2

x/-125-96 - y/-144-(-30) - 1/-72-270

x/-221 - y/-114 - 1/-342

x=-221/-342

x=221/342

y=-114/-342

y=3
