Solve uing the subtitution method. Show your work. If the system has no solution or an infinite number of solutions, stat this,3x15y=12
3x+24y=12

intermediate algebra 
MathMate,
3x15y=12 ...(1)
3x+24y=12 ...(2)
Subtract (1) from (2) to get
39y=0, or y=0.
Substitute into (1) and get
3x+0=12,
or x=4
