3x + 4y = 1/2/3
6x+3y=1/1/4 | :3

3x + 4y = 1/2/3
2x+y=5/12

3x + 4y = 1/2/3
y=5/12-2x

3x + 4(5/12-2x) = 1/2/3
y=5/12-2x

3x + 1/2/3 -8x =1/2/3
y=5/12-2x

-5x=0
y=5/12-2x

x=0
y=5/12

3x+4y=1 2/3 /*(-2)
6x+3y=1 1/4


-6x-8y=-3 1/3
6x+3y=1 1/4

-5y=2 1/12 /:(-5)
y= - 5/12



3x+4*(-5/12)= 1 2/3
x=3 1/3
