You can put this solution on YOUR website!
y=3x-7
\n" ); document.write( "y=-x+1
\n" ); document.write( "We're looking for when their x=x and y=y, so set the problems equal to each other.
\n" ); document.write( "3x-7=-x+1
\n" ); document.write( "3x+x-7=x-x+1
\n" ); document.write( "4x-7=1
\n" ); document.write( "4x-7+7=1+7
\n" ); document.write( "4x=8
\n" ); document.write( "4x/4=8/4
\n" ); document.write( "x=2
\n" ); document.write( "Let x=2 and solve for y in one of the equations.
\n" ); document.write( "y=-(2)+1
\n" ); document.write( "y=-1
\n" ); document.write( "The solution is:(2,-1)
