solve using the elimination method.show your work. if the system has no solution or infintite number of solutions, state this 4x6y=30, 3x5y=24

4x6y=30
3x5y=24
(4x6y=30) Multiply with 3
12x18y=90
(3x5y=24) Multiply with 4
12x20y=96
Now you have System:
12x18y=90
12x20y=96
Subtracting 12x18y=90 from 12x20y=96 gives:
12x12x18y(20y)=9096
018y+20y= 6
2y= 6 Divide with 2
y= 3
4x6y=30
4x6*(3)=30
4x+18=30
4x=3018
4x=12 Divide with 4
x=3
OR
3x5y=24
3x5*(3)=24
3x+15=24
3x=2415
3x=9 Divide with 3
x=3
Solution is: x=3 y= 3
