You can put this solution on YOUR website!
Given system%28-2X%2BY=3%2CX-3Y=-7%29 , you realize that it is a system of linear equations and find the ordered pair of values (X,Y) that satisfies both equations.
This system of equations is easy to solve by substitution,
meaning solving-2X%2BY=3 for Y ,
and substituting the expression found for Y in the other equation:
system%28-2X%2BY=3%2CX-3Y=-7%29-->system%28Y=2X%2B3%2CX-3Y=-7%29-->system%28Y=2X%2B3%2CX-3%282X%2B3%29=-7%29-->system%28Y=2X%2B3%2CX-6X-9%29=-7%29-->system%28Y=2X%2B3%2C-5X-9=-7%29-->system%28Y=2X%2B3%2C-5X=-7%2B9%29-->system%28Y=2X%2B3%2C-5X=2%29-->system%28Y=2X%2B3%2CX=2%2F%28-5%29%29-->system%28Y=2X%2B3%2CX=-2%2F5%29-->system%28Y=2%28-2%2F5%29%2B3%2CX=-2%2F5%29-->system%28Y=-4%2F5%2B3%2CX=-2%2F5%29-->highlight%28system%28Y=11%2F5%2CX=-2%2F5%29%29
