Multiply the first equation by 4
48x+72y= 144

Multiply the secondequation by -6
-48x-72y= -144

Add the equations together
48x-48x+72y-72y=144-144
0+0=0
True

Final answer: Infinitely many solutions
choixongdong
12x+18y=36 (1)
8x+12y=24 (2)

divide (1) by (3) and divide (2) by (2)

4x+6y=12 (1)
4x+6y=12 (2)
------------------subtract 
0 = 0
