You can put this solution on YOUR website!
3X-Y=5
2X+Y=5
You can solve this several ways. One is by elimination, which is how I will solve it;
You add the equations together to eliminate one variable;
3x-y=5
2x+y=5
-------
5x =10
New equation;
5x=10
divde each side by 5;
5x%2F5=10%2F5
x=2
Now that we have what x=, plug that into the equation to find y;
3(2)-y=5
6-y=5
-y=5-6
-y=-1
y=1
So we have;
x=2
y=1
Hope you understand
