2x-3y=6
3x+6y=16
To eliminate the y variable in these equations, multiply the first equation times 2, and add the two equations together:
4x-6y=12
3x+6y=16
7x=28
x=4
Substitute back into either equation:
2x-3y=6
2(4)-3y =6
8-3y=6
-3y=-2
y=2/3
Check by substituting into the second equation:
3x+6y=16
3(4)+6(2/3)=16
12+4=16
This checks!!
